3 »Editorial Wireless on a wire Timing devices Our precision = your design benefits Willem Ongena Forecasts are difficult, especially when they concern the future. Whether this bon mot comes from Kurt Tucholsky, Mark Twain, Karl Valentin, Winston Churchill or someone else: Especially these days, on the world stock exchanges, the political stages and the scenes of disasters, we are repeatedly reminded of how much truth there is it is and how difficult it is for humanity, unchanged, to reliably assess its own future. Even so, most people would like to know what the world of the future will look like. The easiest answer is probably who knows what will change. And in order to find the answer, one can ask oneself again what or who has what it takes to change this world. You don't have to be a technology freak to suspect that it is above all the rapid, sometimes breathtaking technical development that will shape our world in the future. And, as in the last few decades, it will primarily be the “enabling technologies” that will play a leading role here. Put simply, these are all groundbreaking technologies that initiate new trends, simplify our everyday lives, make them more comfortable or safer, reduce costs and so on. These certainly include genetic engineering as well as pharmaceutical and medical innovations. And anyone who speaks of enabling technologies cannot avoid including technologies for the wireless transmission of data, images and audio. What would the world look like without the wireless technologies DECT, GSM, 3G, LTE, WiFi, Bluetooth, ZigBee, GPS, RFID or NFC? Cell phones would not exist and other cell phones would likely have received far less interest. I dare to predict that the world of the future will also be very much based on wireless. Mobile communication will continue to play a dominant role here. But in the same way, all sorts of "things" will be wirelessly networked with one another or a control center. I am thinking of the »intelligent house«, of course without meaning that all electrical household appliances will be networked. But it would certainly be a blessing if seniors could stay in their own four walls for much longer thanks to intelligent radio networks, even at a very advanced age. And how relieving it would be if the beloved pet could still run away or escape, but thanks to radio technology, it could be quickly tracked down again in an emergency. Thanks to intelligent networking, one could also declare war on the energy waste of many small energy guzzlers. And it would also be practical if the millions of heat, gas and water meters installed could be read remotely via radio. Such applications have already been implemented in some cases. And there are no limits to your imagination. However, my imagination is definitely not enough for the variety of possible applications that radio technology will open up to us in the coming decades. With only a little imagination, however, I can predict that constantly updated radio know-how will be an indispensable key to the door to market success. In the meantime, not every application developer will be able to acquire this specialist knowledge. He doesn't have to, as long as there are providers such as Rutronik who specialize in wireless solutions and who are committed to offering a wide range of products and who understand customer needs and applications as well as wireless technologies and their many peculiarities. Then one of the steps into a bright future would be taken, even if we still (and probably fortunately) still have to be surprised at how it really develops in individual cases.

6 Interview of the week Open consultation and a broad product portfolio The right line to wireless With every new wireless technology, new application possibilities arise, but also new pitfalls. Bernd Hantsche, Product Area Manager Wireless Competence Center, explains how to get the best technology and what Rutronik can contribute. Markt & Technik: What advice can you give developers interested in wireless technologies? Bernd Hantsche: Talk to us! It is very common that someone has read or picked up something somewhere and wants to get started right away. Often only one side of the coin was shown and many factors were not considered and examined. There is only rarely the egg-laying woolly milk sow. Therefore, all advantages and disadvantages must be collected in order to be able to make a decision to the best of your knowledge and belief. The first thing to do is to question the basic technology. Only when you have an overview of all the technological alternatives should you use the same decision-making method when choosing a product. I therefore recommend asking for an appointment for a consultation with a specialist from our wireless team. This is free of charge, without obligation and can also be done over the phone or in an online conference room if an on-site visit is not desired. What distinguishes Rutronik from other providers in the wireless arena? Rutronik has many strong manufacturers in its portfolio. We have at least one leading supplier in every technology sector. Our product and application specialists are very well trained and always up to date thanks to regular training. Despite the high quality and depth of the specific expertise, we can still offer an enormous breadth - we cover what feels like 99 percent of all radio applications. Other distributors limit themselves only to GSM or only to RFID or only to short-range radio or offer everything without being able to fall back on trained staff. In which areas or for which standards does Rutronik offer components? Rutronik has divided the “Wireless” area into three departments: Cellular radio technology including satellite navigation as well as short-range radio and RFID. Cellular radio technology is also known as mobile radio, whereby the days are over when GSM, GPRS, UMTS and HSPA are used exclusively in mobile applications. The largest market segments are still telemetry and telematics. Virtually all telematics applications are based on both mobile phone technology and satellite navigation technology, so that both product areas are particularly closely linked with us. Our solutions for satellite navigation consist of receivers for the active systems GPS, Glonass and QZSS as well as already prepared receivers for the future satellites from Galileo and Compass. What about the shorter distances? Short-range radio includes all technologies up to a range of around 16 km. This limit value is due to the legal power limitation of 500 mw in the 868 MHz ISM band.In addition, there are also WLAN / WiFi, Bluetooth, Bluetooth LE, ZigBee, ANT and various proprietary radio solutions that are not subject to any recognized standard. These can be both narrowband and broadband signal modulations, as well as transceivers for all common ISM bands in the world. What does Rutronik offer in the RFID area? Our RFID segment essentially comprises passive and active RFID, NFC and dual interface memories. The latter are memory chips with an interface to the microcontroller and a direct antenna connection. Thus, the EEPROMs or FRAMs can be written via RFID as well as via the controller. This technology in just one chip is still quite new and stands out from classic RFID transponders, which are isolated like an island and cannot be connected directly to other controllers. NFC is a type of bidirectional RFID in the media, often in connection with payment systems. In fact, however, it addresses significantly more areas of application, as many smartphones have already integrated this technology. The upcoming iphone 5 is also equipped with NFC. Bernd Hantsche, Product Area Manager Wireless Competence Center, Rutronik »There is only rarely the egg-laying woolly milk pig. Therefore, when designing and selecting products, all the advantages and disadvantages really have to be considered and the basic technology must also be questioned. The specialists from our wireless team offer competent support. This is non-binding, free of charge and can also be used over the phone or internet conference. «What about the accessories? Our “Wireless Accessories” group includes internal and external antennas, as well as various adapter cables, extension cables, SIM card holders and connectors suitable for our radio modules. Our wireless accessories therefore complement our transceivers from all of the product areas mentioned, so that they are completed for functionality. In principle, no radio transmission works without an antenna. These additional items should not be underestimated. With the wrong antenna, the best transceiver is no good. Therefore, this range of accessories is very important to us. How many products and manufacturers is that in total? Our largest focus lines are Telit, Fastrax, Redpine Signals, Nordic Semiconductor and Infineon in total we can officially name 27 manufacturers as franchise partners, unofficially a few more. We can serve an estimated 99% of all technical tasks on the market with the portfolio. Of course, there are also requirements that we cannot meet today because we do not yet see an attractive market. These would be, for example, DECT, Tetra, satellite communication and classic long-range radio. But even for these technologies we at least have the right antennas and, with the help of our other specialist departments, offer discrete components, filters and amplifiers so that our customers can develop their own transceivers. page

8 Current News Are there any expansions to the range of products to be expected? In the mobile communications sector, the first long-term evolution modules will probably come onto the market in the course of the next year. Whether it will be the 3.9 generation or whether it will already be real 4G modules with LTE Advanced, I don't dare to predict today. We are currently receiving a large number of inquiries about the IT600 from Fastrax. It offers the option of receiving and processing both GPS and Galileo, QZSS and Glonass signals. What services does Rutronik offer besides the products? As a rule, our work begins with an individual consultation. Often the first step is to find the technology before dealing with specific components. There are often questions about certifications, compatibility, longevity and regulations on transmission power, modulations and duty cycles. Only when the customer knows for sure which technology he would like to use in his products do we present our suppliers and their products in detail. After the transceiver has also been found, we offer an introduction to the development kits with the help of our FAEs on request. This saves our customers a lot of training time, which ultimately means a shorter development time and thus faster sales. And what happens after the design is completed? As soon as our customers have designed a layout, we have it checked by high-frequency engineers and send an official inspection report back to the customer, from which he can find recommendations, improvements and tips. If this report no longer contains any information and the customer has produced a prototype, we can also have it measured free of charge in the laboratories of our partners. Although this does not replace measurements by a certification company, costly and time-consuming complaints can be almost completely eliminated. In addition, our customers can use the entire range of services from Rutronik: We offer virtually all types of semiconductor, passive, electromechanical, displays, boards, storage media, etc. Larger customers also like to use our logistics concepts to optimize process costs and increase security of supply from the consignment warehouse via Kanban up to kitting. What are the delicacies of the product range for you? Redpine Signals is still quite unknown in Europe. The Californian / Indian company focuses on WLAN solutions. Redpine offers its own chips, modules, firmware and drivers as well as reference designs and development kits. It is quite unique that a WLAN module manufacturer can use its own chips. Other manufacturers have to rely on third-party chips and therefore have little control and influence over functions and performance. The software for the TCP / IP stack, drivers and analysis tools also come entirely from our own company. We are proud to be able to establish Redpine in Europe as a pan-European partner. Our largest partner Telit has integrated Motorola's M2M division into its portfolio, making it the world's number one in the M2M sector. A close partnership with Rutronik has existed since 2006. At Telit, 3G modules such as UMTS and HSPA + are currently in the foreground. The portfolio is supplemented by wireless M-Bus, ZigBee, GPS and own local mesh network protocols. Which products have been the most popular lately? We are currently receiving a lot of inquiries about the IT600 from Fastrax. It offers the possibility of receiving and processing both GPS and Galileo, QZSS and Glonass signals. On the one hand, word got around that the position accuracy is much better than that of a pure GPS module, and on the other hand, there are no punitive tariffs when the end devices are exported to Russia. The new legislation on the use of Glonass in Russia only plays a subordinate role. The main argument is better performance, regardless of the location. What price developments can be expected in the near future? That is quite different for the product groups. Bluetooth modules are already being traded at a level that sometimes it is difficult to understand how manufacturers can offset material, development and certification costs. We have seen a permanent drop in prices for GSM modules over the past five years. Of course, this takes account of the growing market, but also of ever newer technologies. In the meantime, HSPA + modules are in great demand because with 3G the availability of the infrastructure is not endangered in the next few years. In the meantime, simple 2G modules are being traded correspondingly cheaply, the price of which five years ago was where 3G modules are used today. And what about the delivery times? Fortunately, delivery times are not an issue for us. Due to RF technology, software and certifications, the development phase of our customers always takes much longer than the supply chain from the raw material to our logistics center. We always keep a large range of samples in stock so that our customers can start designing their prototypes immediately. In order not to endanger larger pre-series or mass production, we are in close contact with customers and can thus ensure timely and sufficient availability of goods. Incidentally, this contact occurs automatically during the development phase. Because there are always technical questions that have to be clarified personally despite the best documentation, because they are so individually customer-specific or the answer requires a variety of empirical values. What's the next wireless trend? Smartphones currently support Bluetooth and WiFi, the next generation will also support NFC, Bluetooth LE and ANT. This means that there are many local radio interfaces available that will make life more comfortable and safer. In addition, you save on additional displays and buttons on various end devices, because these can be controlled or operated via smartphone apps. For this purpose, we already offer both radio chips and radio modules for all smartphone technologies. This trend is only just beginning. We Europeans may have to get used to the fact that our telephone will switch on the light in the stairwell fully automatically when entering, our refrigerator contents can be called up via web cam and our family doctor will keep an eye on the blood pressure. You give the impression that you have put your heart and soul into the wireless thing. Yes, that goes for the whole team. Obviously our customers notice that too, because we are growing strongly. That is why we always look forward to reinforcement by engineers with high frequency experience or radio protocol developers. The interview was conducted by Manne Kreuzer

9 Current News Broad portfolio of high-quality components Multilayer inductors and ferrite beads for all industrial applications Due to the extensive experience of Samsung Electro-Mechanics (SEMCO) with MLCCs, a high degree of technology transfer takes place, especially in the know-how of printing processes and the Material properties of ferrite, silver and other materials. With this knowledge, SEMCO builds very low-loss ferrite beads with low DC resistance, high-quality RF inductances and power inductances with a high rated current capacity.Ferrite Beads the all-rounder for filtering The CIB / CIM series have a higher impedance even in the lower frequency range, which enables them to have excellent damping properties over a wide frequency range. The CIM series is suitable for control signal lines, RS232, RS422 and DC / DC converters. Especially with high-speed data transmission via USB, IE-EE1394 and LVDS, the low impedances of the CIM-F series in the low frequency range are decisive for good filter properties and fast signal transmission. In the power line area, the ferrite beads must withstand currents of up to 6A. The CIC series already achieves this load capacity in the 0805 design, the CIS series even with The products of the CIV series have a significantly higher impedance in the GHz range for interference suppression at higher frequencies for applications in the mobile radio segment or for bus signals. Filter inductors to suppress crosstalk The CIL series from Samsung Electro-Mechanics (SEMCO) is based on a ferrite core and a silver coil inside. This magnetically shielded construction prevents crosstalk very effectively. The CIL types are suitable for the discrete construction of T or π filters, as well as for filter and oscillator circuits. High quality inductances even at high frequencies The two most important criteria for high frequency inductances are the quality and the natural resonance frequency. Put simply, these define housing inductance (µh) nominal current (ma) direct current resistance (Ω) Series, 2 10 1.7 CIH, 047 to 33 1 to 50 0.3 to 2.95 CIH, 047 to 33 5 to 300 0, 2 to 1.25 CIH, 047 to 33 5 to 300 0.15 to 1.05 CIH31 the loss factor and the starting frequency of the inductance. The CIH series with an SRF of up to 13GHz is ideal for use above 100MHz. A special dielectric ceramic allows excellent quality even at high frequencies of several MHz. Areas of application for the CIH series are SAW filter circuits, VCO circuits, Bluetooth, W-LAN, filter circuits, digital TV tuners and other high-frequency circuits. Power inductors with high current carrying capacity With a high current carrying capacity from 0.5 A to 3.3 A and direct current resistance values ​​from 0.04 Ω to 0.5 Ω, the power inductors of the CIG series from CIH series are ideal for use at frequencies from 100 MHz Samsung optimal for use in DC-DC converters. Especially at high switching frequencies, the electrical properties of the CIG series are the same as those of wire-wound coils. Inductance values ​​from 0.27 μh to 10 μh (± 20%) are available. The advantages of the power inductors are particularly evident in DC-DC converters for energy storage, EMI suppression and for smoothing the current in power supplies. The main areas of application of the CIG series are primarily mobile devices such as POS systems, battery-operated sensors (smoke detectors, light sensors, etc.) and e-bikes or cost-critical applications with high PCB packing density such as LED drivers, set top boxes and industrial PCs.

10 Latest News Online Wireless Support Webgate, Webinars, Website & Co. When it comes to wireless technology applications, a detailed discussion between developer and product specialist is essential. The large number of different parameters makes a selection based on data sheets alone impossible; it should rather begin with the needs analysis of the software protocol. And it is often only during the licensing and EMC measurements that it becomes clear that another product is more suitable or that a completely incorrectly dimensioned technology has been used. Politics is increasingly becoming a further decision criterion: In addition to technology organizations such as the Bluetooth Special Interest Group, ZigBee or WI-FI Alliance, vertical interest groups such as the Continua Health Alliance are increasingly deciding on compatibilities with competitors. In this complex and innovation-intensive area, extensive, quickly available internet offers support personal discussions with current information, research and exchange opportunities. The Rutronik ecommerce platform combines convenient e-procurement and online services with interfaces to the “offline world”. It contains almost a million products, including well over a thousand wireless components. The highlight for efficient procurement is the sophisticated search function, with which all available identical or similar products can be found. The customer does not necessarily have to enter the product name, but can also choose a term. Labeling according to preferred products, highlight articles, discontinued and demand-driven products also makes selection easier. In addition, each component always appears with its daily Product Change Notifications (PCN) and the relevant data sheets. This gives the user a good overview in order to individually decide which module best fulfills the parameters that are most important to him. Once the optimal component has been found, the customer can place the order or sample order directly online, view his order backlog at any time, transfer it to his own IT system via Excel and compare it in the simplest possible way. The technical support is not neglected: questions can be asked via an online form, which the responsible product manager answers immediately by.

13 Topic of the week Medical radio technologies for telemedicine Modern »Flying Doctors« Around 500 million people will use wireless medical applications and access health or medical apps by 2015, according to elektroniknet. A large number of technologies are already available for this. Photo: Fotolia Technologie Download Upload EDGE 220 kbps 110 kbps UMTS 384 kbps 128 kbps HSDPA / HSUPA 7.2 Mbps 5.76 Mbps HSPA + 28 Mbps 11.5 Mbps LTE 100 Mbps 50 Mbps LTE Advanced 300 Mbps 75 Mbps max Smartphones are ideal as a display and input interface for external devices because they have integrated Bluetooth, WLAN and UMTS. UMTS, used here as an umbrella term for cellular connectivity, is suitable for any large communication distance, as long as a base station of a cellular network provider is nearby. Health values ​​can thus be saved, evaluated and analyzed at any location. The chips used are backwards compatible with GPRS and EDGE. Although this means a slower data connection, it also means practically uninterrupted network coverage. Most smartphones even support the faster standards HSDPA, HSUPA or HSPA +. Unfortunately, the UMTS network expansion in Germany is only really good in metropolitan areas, but the expansion with LTE and LTE Advanced is already underway and should soon achieve the greatest possible population coverage in this country. This internet connection for smartphones is particularly popular with healthcare applications that connect to smartphones using short-range radio. Bluetooth and WLAN are available for tasks involving short-distance connections. WLAN, or WiFi, already allows high data rates and the integration of smartphones into existing WLAN networks. This means that health values ​​at home can be sent from a measuring device via WLAN to the in-house router, which transmits the data packets to the service provider via DSL. The complex frequency modulation (mostly 20 MHz plus scatter) and large Internet protocols, which are mostly used by IEEE, drive up electricity consumption. As a permanent wireless solution without a fixed energy supply, WLAN is therefore unsuitable. Bluetooth is more economical: Here the channel bandwidth is only 1 MHz, and the profiles require significantly less overhead due to the lack of network capability. The advantage of integrating Bluetooth and WLAN in medical devices is obvious: an app for the smartphone and a Bluetooth or WLAN-capable radio module for the medical device are sufficient, and the machine-to-machine (M2M) radio connection is ready. This compatibility is thanks to the associations of interest groups who set the appropriate standards. "The downside, however, is that such standards are always a compromise between different requirements," explains Bernd Hantsche, Product Area Manager Wireless Competence Center at Rutronik. "That means: neither WLAN nor WLAN Bluetooth were specially developed for blood pressure monitors. Addressing, security mechanisms and other overhead must be taken from the specifications, even if they are oversized for the actual task. «Proprietary wireless solutions such as the Gazell protocol from Nordic Semiconductor or the MiWi protocol from Microchip. "When choosing, it is important to weigh the technical advantages and the higher energy efficiency against the compatibility." Bluetooth with lower energy consumption Nordic Semiconductor started working closely with Nokia a few years ago to develop a universally applicable, more energy-saving wireless solution than Bluetooth to develop. Originally known as "wibree", this protocol is currently marketed as "bluetooth low energy" or "bluetooth LE". Together with Bluetooth 3.0, the result is Bluetooth 4.0, which will be found in smartphones, laptops and the like in the future. "Depending on the data to be transmitted, there is a choice of devices with Bluetooth 2.0 or 2.1 or Bluetooth LE on the application side," so Hantsche. »For example, a hands-free system requires the enhanced data rate, for which Bluetooth 2.0 or 2.1 would be the method of choice. A bathroom scale or a blood pressure monitor, however, only transmits a few bytes, so that Bluetooth 2.1 would be completely oversized: The hardware costs, energy consumption and licensing costs are unnecessarily high. Bluetooth LE enables a much longer battery life, is cheaper and will soon be available as a standard just like the current Bluetooth version. «ANT: Energy efficiency for sports and medical applications In order to find a solution with low energy consumption especially for healthcare, sports and wellness applications, Dynastream developed ANT. The ANT protocol mainly covers the network and transport layers, the ANT + profiles optionally implement the presentation layer above. Requirements for using the

14 Topic of the week Medical ANT + Profils is membership of the ANT + Alliance or the purchase of a development license. "Anyone who waives direct support and certification can develop with ANT + free of charge since the beginning of 2011," says radio technology expert Hantsche. As with Bluetooth and WLAN, the protocol's hardware basis is the 2.4GHz ISM band, which can be used worldwide without a license. In contrast to these, however, ANT + uses signal modulation according to the Gaussian Frequency Shift Keying method (GFSK), which requires less energy to form the zeros and ones than spread spectrum modulations, such as those used in e.g. Use IEEE based solutions like ZigBee and MiWi. Theoretically, amplitude modulations are on average more economical than frequency modulations. The more error-prone demodulation increases the latency of the transmission, since some packets have to be sent repeatedly and the transmission power is increased in the process. Embedding the HDP in a Bluetooth system This would worsen the overall energy balance. In contrast to Bluetooth, ANT does not need to change channels unnecessarily. While Bluetooth changes the channel 1600 times per second to ensure that a free channel can be used again and again, ANT only changes the communication frequency when there is actual interference. This as well as many other differences, especially in the protocol structure, make ANT very attractive for battery-powered and rechargeable-battery-powered devices. It is not without reason that there are already many well-known manufacturers in the ANT + Alliance, including Garmin, Adidas, Brooks, Timex and McLaren. The first nine places of the Tour De France 2009 were occupied by riders with sports equipment with ANT + technology.So far, only the XPERIA mobile phones from Sony Ericsson and models from some special manufacturers support ANT. ”Although ANT is also very interesting from a technological point of view for other industries, due to the licensing monopoly, it will probably only make the big breakthrough in medical and healthcare applications, as that Protocol has already established itself here as a quasi-standard ", so Hantsche's assessment." If you look at the efforts Apple is making to enforce its own standards as a "must have" in an industry, ANT has done this faster and more efficiently, probably because it is on has waived expensive licenses and the protocol has already been paid for with the purchase of the transceiver chip. «Interest group for medical applications Modular structure of Zigbee The Continua Health Care Alliance was formed in order to establish standards that are especially optimal for telemedical applications. It defines, for example, the communication interface between the data collector, internet server and analysis service or the connection of sensor applications to the data collector, such as blood pressure monitors, personal scales or blood glucose meters. Depending on the device, the ZigBee Health Care or Bluetooth Health Device (HDP) profile is available. Since ZigBee always needs a coordinator, it is more suitable for meshed sensor networks; Bluetooth is more suitable for classic point-to-point or point-to-multipoint connections (piconet) of smaller networks due to its limitation to seven participants. For most medical applications that are operated by the patient, Bluetooth LE is most interesting:

15 Topic of the Week Medical Low costs, minimal power consumption, peak currents suitable for button cell use, worldwide frequency standardization and, thanks to the Bluetooth SIG, good marketing speak for themselves. For professional medical devices, Bluetooth HDP can be expected to catch on. The lower latency thanks to frequency hopping is an important argument for which the higher energy consumption is accepted. The transceiver technology, the processing of the more extensive protocol stack and the more extensive certifications are also less important in the professional field. The Bluetooth SIG guarantees compatibility. The trend: radio-capable system-on-chips There are also several possible solutions for implementation at component level: In addition to pure transceiver chips, which require an external microcontroller to process the radio protocol, many developers use certified radio modules. The integration levels differ considerably, the most popular are modules with antenna, controller, quartz, programmed Bluetooth ID and the usual certifications. Radio-enabled system-on-chips (SoCs) are a new trend, especially in medical devices. They not only contain the radio and a controller including radio stack, but also a high-performance analog circuit part with AD and DA converters, PWM, display control and many other features and interfaces. »Compared to a structure with individual components, an SoC offers enormous cost advantages, but has fewer Requires space and requires less logistical handling when procuring components, ”explains Bernd Hantsche. Since failure safety has a particularly high priority in medical technology, it makes sense to keep the number of components and thus the number of error sources as low as possible. This also speaks in favor of wireless system-on-chips, such as the particularly powerful Infineon MD8710, but also the smaller Infineon PMA5110, Nordic nrf24le1, ST STM32W or Renesas M16C / 6B. Understanding medical applications The snapshot shows that wireless technologies are constantly evolving, both in terms of hardware and software. This makes it difficult for developers to always keep track of things. In addition: When deciding on a technology, (corporate) political aspects also play a role in addition to commercial and physical decision-making factors. For the future viability of an application, it is crucial to know which technologies competitors in the market or the IT industry are relying on. In order to be able to provide qualified answers to questions like these and to offer developers of medical applications the best possible support, the distributor Rutronik has set up the "vertical Market Team Medical". The team of technology specialists for semiconductors, passive components, wireless, displays, embedded boards and electromechanics deals intensively with the medical market, knows the specific requirements of customers, the trends in the industry, all relevant regulations and political tendencies. In addition to the technical specifications, price considerations and availability, these aspects are also included in the advice, and the customer not only receives a technically functioning solution, but a future-oriented application with which he can still assert himself in the market tomorrow. telit2market OUT NOW!

16 Topic of the Week Medical Highly integrated single-chip solution Many requirements - one solution What do glucose, blood pressure and ECG measuring devices, ergometers and devices for blood analysis have in common? In terms of their area of ​​application and their function, not much, but a lot in terms of their basic electronic structure. All of these functionalities can now be found on a single chip. With it, developers can bring more compact and cheaper devices to market maturity more quickly. Almost all laboratory, diagnostic or therapy devices have keys for input, a display for displaying data, communication options, a data memory, interfaces for sensors, loudspeakers and a power supply. They are usually resolved discreetly. For example, a classic, portable glucose meter consists of twelve integrated QFP components and another 30 to 50 discrete components. Selecting the ideal components for this and coordinating them with one another entails a long development time. In addition, it takes a lot of effort to achieve a compact design. To remedy this, the distributor Rutronik has developed a System-on-Chip (SoC) together with Infineon, which currently has the highest degree of integration of the medical ICs available on the market: the Single Chip Medical Device Fig. 1: Basic structure of a modern medical technology Device MD8710. It reduces the number of components to 3-5 ICs and approx. 15 to 30 discrete components. This cuts costs by a good half, because the market price of the individual ICs required is more than twice as high as that of the MD8710. At the same time, the development time is reduced due to the significantly lower selection and coordination effort. The platform concept offers further savings: Thanks to the flexible configuration of the MD8710, several devices can be implemented on one platform. A wide variety of applications can be implemented by simply exchanging the sensors and making minor software adjustments. In this way, expensive development time can be saved again and the "time-to-market" for new devices can be shortened significantly. One for all: Single Chip Solution The heart of the Single Chip Medical Device MD8710 is a powerful ARM Cortex R4 processor. It is accompanied by a comprehensive memory protection unit, an interrupt controller, a DMA controller and a watchdog timer. The analog front end of the module offers developers a lot of flexibility, as different sensors can be connected, for example a simple EKG electrode with a low voltage swing of a few mV as well as an IC-based sensor with voltages of 2.5 V. In addition, the MD8710 enables devices with high demands on analog signal processing: It has two independent 16-bit ADCs and two 16-bit DACs, whereby the DAC channels can be supplied with data from an integrated »wavetable«. Additional DSPs are no longer necessary. Two configurable OPs per ADC offer the option of analog preprocessing, e.g. Transimpedance amplifier for current inputs. For further system integration, Figure 2: Block diagram of the Infineon MD8710 MD8710 contains a 12-bit ADC with four external auxiliary multiplex inputs and a temperature sensor. The possibility of synchronous sampling of the ADCs also allows complex measurements, e.g. impedance spectroscopy for blood analysis. The Power Management Unit (PMU) generates all the necessary voltages with a few external components and simultaneously monitors all internal supplies. She masters various energy-saving and wake-up scenarios and is responsible for the charge control of a LiIo or LiPo battery. For security purposes (e.g. battery authentication), an interface for an externally connectable ORIGA chip from Infineon is integrated. The MD8710 also has a display controller that supports matrix LDCs. A class D output stage is used to control a loudspeaker, devices can use it to output voice messages in addition to simple, classic beeps. The real-time clock serves as a time stamp for

17 Fig. 3: Discrete structure of pulse oximetry Fig. 4: Integrated structure of pulse oximetry with the MD8710 Topic of the Week Medical Determine the Blood. Due to the constant absorption of the tissue, there is a high DC signal component, the pulsating blood causes the AC signal component. The exact size of the AC and DC components is strongly dependent on the light intensity and the absorption of the tissue. Due to the variable blood flow in the tissue, a very high fluctuation of the AC component is possible, which can range between 0.01% and 10% of the DC component. In order to still be able to draw conclusions about the hemoglobin proportions, the best possible DC compensation is essential. In the first step, the pulse oximetry signal is present as a current signal through the photodiode (measurement of light absorption). A transimpedance amplifier converts this into the required voltage signal for further processing. This is followed by the described DC compensation, which is implemented via a further OP stage. In the discrete structure, this results in the principle diagram shown in Figure 3.When setting up with the MD8710, almost all discrete components are superfluous, because it can perform all functions important for pulse oximetry. The dynamic of the absorption is in the range between 50 and values ​​(14 to 15 bits). However, only a limited area is necessary for the detailed analysis. Since the delta-sigma converters of the MD8710 are specified with 16-bit resolution, error-free conversion is guaranteed and pulse oximetry can be implemented without any problems. A noise error analysis carried out confirms this result. data logging and regulates time-controlled processes. A USB 2.0 interface, I 2 C, SPI and UART interfaces as well as a Bluetooth module integrated in the chip are available for data exchange. The USB connection allows remote control of the device from a PC and the transfer of the measurement data to the PC, where it can be displayed and edited. Parameters saved on a USB stick can be used to automatically set the device; the stick can also function as a data logger. With the help of the additional Bluetooth connection, the data can also be transferred to a smartphone. The MD8710 can be used to develop devices that meet the standards of the Continua Health Alliance (www.continuaalliance.org). It already has over 200 well-known companies that have developed common guidelines for a so-called "personal healthcare ecosystem". It describes a closed system within which the measuring device sends the recorded data to a local collection point, where they are saved. So that the user can call up and display his data and initial evaluations from here with the PC in the same way as with the BlackBerry or iPhone, the measuring devices should be equipped with a simple and general interface, such as USB ports, Bluetooth, Zigbee or WiFi Interfaces. Users can then transfer the data from their PC or cell phone to health platforms, where they are available to doctors or therapists, for example. Application example pulse oximetry Using pulse oximetry, the difference between a discrete and an integrated structure becomes clear. A pulse oximeter measures the light absorption during fluoroscopy of the skin on the finger using two different light wavelengths: On the one hand in the infrared range at 940nm, since this is where the absorption maximum of the oxygen-saturated hemoglobin (HbO 2) lies. The second wavelength is 660nm, here the hemoglobin (Hb), which is not saturated with oxygen, absorbs the most light. The oxygen saturation can be determined from the ratio of the two measured values. Application example ECG With ECG measuring devices, the MD8710 allows the processing of the electrode signals by connecting the internal operational amplifiers to an instrumentation amplifier in front of the ADCs. Synchronous measurements compensate for possible interference signals and guarantee clean measurement results. Thanks to the integrated driver, they can be visualized on a display. The powerful CPU evaluates the measurement data in real time and alerts the nursing staff or the attending physician when defined threshold values ​​or data patterns are reached. Like pulse oximetry or EKG measuring devices, almost all medical applications can be implemented with the integrated MD8710 solution, which can be seamlessly integrated into a personal healthcare ecosystem. The cost savings on the component side are so high that even the redesign of existing discrete solutions is often possible and useful. Thanks to the large number of integrated functionalities, the devices open up new market opportunities. Further information on the module can be found at:

18 in focus Automotive New receiver module from Fastrax Hybrid position determination with GPS and GLONASS Nowadays, more and more GPS receivers are used in navigation devices, smartphones, in car alarms or in sports equipment. GPS has become the standard in position determination and has therefore become a synonym for satellite-based position determination. There is more to this than just GPS. At least three or four so-called Global Navigation Satellite Systems (GNSS) are known. One of the most famous is GLONASS. While GPS is maintained by the US, GLONASS is of Russian origin. Today, GLONASS achieves an accuracy in the range of 5 meters, while commercially available GPS receivers achieve an accuracy of 2 to 3 meters. Both systems are working on a higher accuracy. Hybrid position determination If a receiver uses more than one satellite system for position determination, one speaks of hybrid position determination. The advantages of such a procedure are obvious: If both the GLONASS and the GPS system are used, more than 50 satellites are available. Such a receiver can usually find a sufficient number of satellites even in densely built-up urban areas. Hybrid systems achieve an accuracy of up to 1.5 meters on a clear sky. The greatest advantage, however, is the precise position determination in situations in which a single system provides unusable results due to satellites that are too less visible. The third benefit of hybrid positioning is safety. Should a GNS system fail, a GLONASS + GPS receiver can maintain navigation thanks to the functional system. Receiver module for GLONASS, GPS and Galileo Fastrax recently released a new receiver module that supports multiple GNS systems, in particular GPS, GLONASS and Galileo, the upcoming European system. The Fastrax IT600 currently enables position determination using GLONASS and GPS, to be followed by support for other satellite navigation systems. The IT600 is no bigger than a normal GPS receiver, but improves navigation quality and accessibility through hybrid positioning and also supports dead reckoning to downtown Dallas. Screenshot of the GPS work surface. 20 satellites in position contact. Continuous positioning when no satellites can be received (e.g. in a tunnel). Hybrid GLONASS and GPS receivers such as the Fastrax IT600 can be used in many applications where the availability of the position is important or the accuracy of the position determination is important for the operation of the device, such as tracking devices or applications for finding stolen vehicles. Pure GPS Devices vs. Hybrid Receivers To determine the impact of satellite visibility in both systems, Fastrax tested both systems in central Dallas. Here the gorges of the high-rise buildings offer ideal test conditions. There were: the IT600 and a leading »pure« GPS receiver. In both test arrangements, the antenna was covered in a car. The result: The solution, which works exclusively with GPS, deviated more than a hundred meters from the actual position. The IT600 determined the position far more precisely using GPS and GLONASS and mapped the actual route. Sometimes the so-called space vehicle count, i.e. the number of available satellites, was twice as high as with the pure GPS solution. Further information: Fastrax Ltd.

19 in focus Automotive Rutronik and Scorpion Automotive develop new tracking platform for vehicles On the right track For the first time since 1993, the number of stolen vehicles in Germany has risen again, according to German insurers (GDV). So that vehicle owners don't suddenly find themselves among the victims of theft, Scorpion Automotive has developed a new tracking platform for vehicles. Thanks to the support of Rutronik, the manufacturer can now offer an inexpensive, technologically highly developed system. Scorpion had clear goals for the new vehicle tracking platform: It should be a microcontroller (MCU) -based system that is characterized by low power consumption, is compact and robust - and at a price that is aggressive to the competition in the automotive aftermarket . With these specifications, the automotive specialist turned to Rutronik to recommend and calculate components for the solution. The core components that Rutronik had to select included a GSM and GPS module as well as the microcontroller. For the GSM slot, Rutronik chose the GE864-QUAD module from Telit. "It is a small quad-band module that is economical to use, has an extended temperature range and has proven to be very reliable and competitive," explains Lee Trueman, Field Application Engineer at Rutronik. "In addition, its flat BGA housing contributes to a significant reduction in production costs and a reduction in the space required for PCB assembly." For GPS capability, Rutronik advised a UP500 GPS- Fastrax receiver module. With its integrated GPS antenna, it offers excellent navigation properties, easy installation in the host system and represents a compact, powerful and inexpensive solution overall. Thanks to its high reception sensitivity, it enables fast position determination in narrow street canyons or other environments with a restricted field of vision, see above that an external antenna could be dispensed with. In order for the receiver to work and to output the serial NMEA data, only a power supply is required. The module also supports dedicated control commands for external control of the operating status. The UP500 has integrated PCB mounting flanges and I / O pin connectors with a standard pitch of 2.54 mm, which make mounting on the host PCB easy and secure. The Fastrax UP501 is the current successor to the UP500. It offers an even higher sensitivity due to the chipset MT3329 with 148 dbm (cold start detection) and 165 dbm (navigation). Therefore, the UP501 can also determine the position indoors if necessary. Compared to its predecessor, it also offers a lower power consumption of 75 mw at 3.0 V and small dimensions of 22mm x 22mm x 8mm. The microcontroller comes from Microchip: a high-performance 16-bit MCU with Flash / RAM, extended temperature range and improved system robustness, which is unmatched by any competitor in terms of price or specification.Scorpion Automotive Comprehensive support makes development child's play "Rutronik provided us with exemplary support by providing us with all the relevant data, such as application notes, data sheets or user manuals," says Peter Stone, Design Engineer at Scorpion Automotive. "The Rutronik Field Application Engineer Lee Truemann visited us regularly, brought samples and provided the Telit evaluation kit as well as valuable advice on the software and testing the components. Rutronik offered competitive prices and supplied us with components for test purposes and took care of the analysis of the pre-series. Thanks to this extensive and competent support, we were able to approve the components very quickly and without problems. «Scorpion approved the components selected by Rutronik within just a few weeks. Immediately afterwards, Rutronik delivered the first production volume for field tests. After these were successfully completed, Scorpion started series production. Scorpion Automotive, based approximately 20 miles north of Manchester, England, is a leading supplier and manufacturer of vehicle security and alarm systems as well as electronic devices for the automotive industry such as radar / microwave sensors, LED units etc. for the OE and aftermarket. Since 1973, his in-house hardware and software team has offered support in creating concepts for prototype development through to mass production in his own SMT production facilities. Scorpion is an approved supplier of Subaru, Iveco, Ford, Renault DAF, Aston Martin, etc. Not without a trace The Scorpion tracking system "Scorpion Track" offers insurance-approved, precise GPS tracking for stolen vehicles and a 24-hour web-based, worldwide access. If the system detects illegal movement, it discreetly informs the international Scorpion control center of a possible theft. Scorpion Tracking tracks a vehicle that has triggered such an alarm until it is retrieved or until a false alarm is confirmed. If the theft is confirmed and the police have issued a reference number, Scorpion employees will contact the police to arrange for the vehicle to be retrieved. When Telit launched the GE864-QUAD-V2, a cheaper and lighter version of the GE864-QUAD previously used by Scorpion, the adaptation to customer concepts was carried out very quickly and without great effort in order to save further costs. Scorpion was thus able to promote the spread of their tracking system. Although the UK economy stagnated in 2011, Scorpion Track sales have grown stronger and better. In May 2011, with the support of the main suppliers, Rutronik succeeded in finalizing a major contract that consists of supplying Scorpion with wireless components and microcontrollers in large quantities. ”We chose these parts from Rutronik because it is the largest The strength is to provide experienced and competent technical support on site that exactly meets our needs. This is underpinned by the good relationships with the market-leading manufacturers, "emphasizes Scorpion development engineer Peter Stone
