3 EDITORIAL Despite all the skepticism: The IoT deserves a chance Are you skeptical about buzzwords such as IoT or Industry 4.0? Then you are not alone: A good number of decision-makers in the German economy think like you. A current survey by Deutsche Messe Interactive and the network specialist Brocade showed that 21 percent of the decision-makers surveyed are of the opinion that Industry 4.0 is not yet relevant to them. Another 24 percent consider the term Industry 4.0 to be too vague, which explains the uncertainty surrounding the implementation of the topic. Even for some technicians, the IoT is a mockery of traditional engineering principles. The networking of everything with everything is, for example, diametrically opposed to the tried and tested principle of parts and rule, which is about breaking down complex systems into small, and therefore more manageable, units. And, to be honest: As long as piles of paper with all-encompassing specifications are being produced in the typically German regulatory madness on the subject of Industry 4.0, no one should be surprised when leaner, pragmatic approaches win the competition of ideas in the IoT. I look forward to seeing you at the IoT Congress on September 14th and 15th in Munich (Franz Graser, editor, however: The potential of the IoT is enormous.

6 ELECTRONIC MIRROR // NUMBERS, DATA, FACTS NOTE: Ruben de Rijcke / WikimediaCommons August 12, 1981: The IBM PC 5150 IBM has dominated the mainframe market since the 1950s, but the development of small computers was initially underestimated. At the end of the 1970s, Big Blue had to watch as companies like Apple, Commodore or Tandy pushed into the market and conquered it. Therefore, in August 1980, a team of 12 led by Philip Don Estridge was given the task of producing their own personal computer within a year. In order to meet the deadline, the developers mainly resorted to already available components from third-party manufacturers: The main processor Intel 8088 was an easily accessible standard chip, extensions were added via breadboards in 5ISA slots. The PC-DOS operating system was not written by the company itself, but was licensed by a small software company called Microsoft. From 1984 the IBM PC and its successors established themselves as the office standard, not least because other manufacturers could easily replicate them and put their own compatible PCs on the market at low cost. // SG 6

8 ELECTRONIC MIRRORS // SEMICONDUCTOR TRENDS Structural miniaturization according to Mooreist until 2021 dead With the traditional Moore law it will be over by 2021, predicts the Semiconductor Industry Association (SIA). 3-D integration processes are replacing the classic 2-D scaling of transistors. Moore's law, according to which the number of transistors on a chip doubles at regular intervals and the efficient performance increases accordingly, has been declared dead several times in the past. One of the reasons for this is that chip development according to this principle in the classic sense depends on how finely the structures can be manufactured. The planar scaling of transistors and the reduction of their distances from one another on silicon is becoming more and more difficult and is increasingly reaching the limits of what is physically possible. It should be over by 2021 at the latest. Moore's law is dead long since Moore's law. The 2015 International Technology Roadmap for Semiconductors (ITRS) of the Semiconductor Industry Association (SIA) comes to this and other conclusions. Because even if the limits of classic 2-D scalability are reached, new technologies such as 3-D stacking will be able to continue to maintain the prediction made by Gordon Moore; however not purely about the structure reduction. The report bases its statement on the fact that the meaning of Moore's Law has changed over the years, but that the essence of the statement has been preserved. However, a fundamental change has taken place in the industry itself. Originally it was the case that block manufacturers drove technological change and device manufacturers used their knowledge and advances to develop their products. However, these signs have changed: The industry is increasingly being driven by device or SoC-centric models, for whose requirements an increasing number of fabless chip manufacturers are specifically producing new, better IPs and components. Smartphone development or the Internet of Things, for example, are extremely shaped by the fact that chip developers are able to handle an increasingly large number of From 2-D interconnect to 3-D stack: According to ITRS, new integration options should drive semiconductor production in the future. Above all, knowledge from memory and SoC manufacturers comes into play here. To combine peripherals as well as memory and high-performance processors in just one component. New technologies and materials on the advance First steps towards new manufacturing methods have already been taken. Memory manufacturers in particular, such as Toshiba with its 3-D NAND stacking, are already operating the first technologies for 3-D integration for their manufacturing processes. Between 2021 and 2024, says the ITRS, the first processors will also be manufactured using 3-D techniques. Manufacturers of memory modules have always been leaders in the production of semiconductors with the tightest tolerance and smallest dimensions, says the SIA report. They were the real driving forces behind Moore's Law and will remain so in the future. According to the report, more and more manufacturers will integrate materials other than silicon into their components within the next six years. Silicon-germanium alloys or other examples of III-V semiconductors using materials from groups III and V of the periodic table (such as gallium arsenide GaAs), which are currently mainly used in power semiconductors, will therefore tend to become the norm from 2021 onwards. The first steps have already been taken in processor production: In 2015, for example, IBM presented a first test chip with a 7 nm structure size based on silicon-germanium. Moore's Law is dead long live Moore's Law The conclusions from the ITRS are that improved processor performance lies in new architectures that are manufactured with the help of 3-D integration processes, optimized multithreading and application-specific cores and generally improved memories. In contrast, the times of simply reducing the distance between transistors and steadily increasing the clock rate should be over in five years at the latest.

Image: Analog Devices The merger of AnalogDevices and Linear Technology brings together the two strongest companies in the semiconductor business, explains Vincent Roche, President and CEO of Analog Devices. We create an unparalleled innovation and support partner for our customers in industry, the automotive sector and in communication infrastructure, Roche continues. Both companies serve the same markets: industry, automotive and communications infrastructure and have a similar product portfolio that now includes interface modules, amplifiers, converters, clock generators, HF and power management solutions. Adi benefits greatly from Linear's position in the power sector Management, the brand will remain in the future. The analog specialist expects the market to double from $ 8 billion to $ 14 billion. Bob Swanson, CEO and co-founder of Linear, added: By combining our complementary technical strengths, we have an excellent opportunity to strengthen our leadership in analog and power in the semiconductor market. Vincent Roche will become CEO of the merged company and David Zinsner, SVP and CFO of ADI, will support the combined company in this position. The leadership will consist of members from both companies. The acquisition is expected to be completed in the first half of 2017. // KR Analog Devices 3-D PRINTING Optical lenses, almost as fine as a hair With 3-D printing, micro-lenses can be produced that consist of several lenses. Researchers at the University of Stuttgart have combined a short-pulse laser with optical photoresist to produce lenses that are barely larger than the diameter of a hair. For this purpose, a laser with a pulse duration of less than 100 femtoseconds is focused using a microscope into a liquid photoresist that has previously been applied to a glass plate or to a glass fiber. Two photons of the laser beam with a wavelength of 785 nanometers are simultaneously absorbed at the focal point and expose it. This hardens the photoresist. With a scanner or by moving the substrate in all three spatial directions, the laser beam can follow the desired shape that is to be produced. This enables optical freeform surfaces to be produced with submicrometer accuracy.The precision makes it possible not only to manufacture spherical lenses, but also surfaces such as paraboloids or higher-order aspheres. Multi-lens lenses for images of the highest quality are also possible. The doctoral student Timo Gissibl from Professor Harald Giessen's group at the 4th Physics Institute printed such micro-objectives on glass fibers. This allows flexible endoscopes to be realized that penetrate into the smallest body orifices or into machines. // FG University of Stuttgart Size comparison: submicrometer triple lens compared to the compound eyes of an ordinary housefly.

Image: Pixabay At the beginning of August, a Lufthansa Airbus A321, which was approaching Munich Airport, narrowly escaped a collision with a drone. According to a report by Bayerischer Rundfunk, the meeting took place at an altitude of around 1700 meters above the town of Schwabhausen in the Dachau district. The Lufthansa Airbus with flight number LH 116 was occupied by 110 people. According to media reports, one of the pilots of the aircraft discovered the unmanned aerial vehicle while looking out of a side cockpit window. The quadrocopter had therefore approached the right wing tip of the Airbus to about ten meters. Markus Wahl, the spokesman for the cockpit pilots union, called for consequences. Against the background of the danger to air traffic from the unmanned missiles, the spokesman for the pilots' association called for more education for the drone operators and technical devices so that the missiles in the vicinity of airports cannot even ascend or fly higher than 50 meters. However, Thursday's near-collision did not occur in the immediate vicinity of Munich Airport; Schwabhausen is about 32.5 kilometers as the crow flies from Franz-Josef-Strauss-Airport. However, the place is in the approach path of Munich Airport. // FG Cockpit Association 10

16 SERIES // POWERTIP Interference caused by switching frequency and switching transitions FREDERIK DOSTAL * Pictures: Analog Devices Fig. 1: Switching frequency and switching transitions of a step-down controller Fig. 2: Filtering of disturbances caused by the switching transitions with a ferrite. When designing power supplies with switching regulators, great care is required, especially in sensitive applications such as measurement technology or high-frequency technology. A switching regulator causes certain disturbances in the system due to its periodic switching behavior. These result from pulse currents and voltages which a switching exciter generates due to the concept. In order to keep the disturbances as low as possible, a good circuit board layout is essential. Different filters are used to minimize the impact of any disturbance that is generated. Various methods are suitable for filtering supply voltages. Linear regulators with a high power supply rejection ratio (PSRR), LC filters or ferrites are used. In order to select the appropriate filter, it is important to know the interference frequencies. It is often assumed that switching regulators only cause interference through the switching frequency. Thus, the switching frequency of the different power supply ICs is carefully considered. Nowadays it is usually between 500 kHz and 3MHz for power supplies without a transformer. * Frederik Dostal ... works in technical management for power management in industrial applications at analog Devices in Munich. However, the switching frequency is only half the story. Another cause of malfunction is the switching transitions of the switching regulator. The switching of current flow during the on time and no current flow during the off time takes place at high frequencies. This switching causes interference in the range from 20 MHz to approx. 300 MHz. Modern switching regulators have particularly short switching times in order to reduce switching losses. Switching transitions of the switching regulator They cause interference of a few hundred MHz. Depending on the switching regulator architecture, the exact frequency also depends on the input and output voltage of the power supply. Information on this interference frequency can not be found in the data sheet of switching controller ICs, so the interference caused is often not expected and therefore not fought in a targeted manner. Figure 1 shows the cause of the switching frequency of a switching regulator as well as the much faster frequency of the switching transitions. This behavior can lead to malfunctions in the system. In addition to these two fundamental frequencies, one also receives periodic multiple signals in the frequency domain. Interference caused by the switching frequency can be reduced relatively easily with linear regulators or LC filters. In the range between 500 kHz and 3 MHz, linear regulators have a fairly high PSRR and can filter well. With LC filters, low-pass filters can also be optimized very easily for the frequency range below 500 kHz and 3 MHz.Ferrites are particularly suitable for effectively reducing the high-frequency interference caused by the switching transitions. Figure 2 shows a step-down switching regulator with a suitable filter, which has been optimized for the high switching transition frequencies of 100 MHz, for example. The filter consists of a small ferrite and a small capacitor. A ferrite has a certain impedance curve over frequency. In Figure 2 a ferrite was selected which has an impedance of 100 Ω at 100 MHz. A linear regulator would not be able to filter effectively and reduce interference at such high frequencies. Another very important aspect with any type of filter, especially when filtering the high frequencies of the switching transitions, is a clean ground reference. In Figure 2 the ground connection of the system is shown in blue. High-frequency interference on this line would be coupled to the supplied circuit regardless of the filter shown in Figure 2. So-called ground bounce is to be ensured in particular by a generally optimized circuit board layout and optimized routing of the mass flows. // KR Analog Devices 16

A secure out of band (OoB) Bluetooth pairing and proximity applications based on BLE IoT systems are of growing interest. Both fields of application are described in more detail here, just as the latest semiconductor solutions and tools can simplify their implementation. Toshiba supplies simple semiconductor solutions for out-of-band pairing and bluetooth beacons. 18th
19 EMBEDDEDCOMPUTING // DATA COMMUNICATION Bluetooth LE and NFC for secure connection and easy pairing Bluetooth Low Energy and NFC stand for fast data transfer and low energy consumption. Both of these alone carry certain risks. Out-of-band pairing dramatically increases the security of connections. HEINER TENDYCK * Pictures: ToshibaElectronicsEurope Reference design: Combined BLE and NFC design based on Toshiba's TC35670 Bluetooth Low Energy + NFC Tag IC, Bluetooth and NFC antenna Bluetooth Low Energy (BLE) is the energy-saving successor version of Bluetooth that is used for the Internet of Things (IoT) was developed. Bluetooth SIG (Special Interest Group) improved its BLE technology with the launch of version 4.2 in December 2014. This version offered additional functions such as improved data cyphering, support for the Internet protocol and faster speeds compared to version 4.1. The further developed specification Bluetooth 5 was announced for the end of 2016. Classic Bluetooth * Heiner Tendyck ... istprincipalengineer, System LSI MarketingDepartment Wireless Solutions, Toshiba Electronics Europe offers advantages such as long range, is omnipresent and can be implemented cost-effectively. BLE ensures significantly lower power consumption, making it suitable for battery-powered mobile and wearable platforms that master the IoT. Modern devices such as smartphones offer the BLE function as standard. Near-Field Communication (NFC) is also being added more and more frequently. NFC enables payments or access control as well as security-related functions if Bluetooth communication could be intercepted by hackers. This is known as the Man in the Middle (MITM) scenario. NFC offers radio transmission that differs significantly from Bluetooth. The transmission distance with NFC is up to 10cm. The amount of data that can be transmitted with NFC is limited and is strictly controlled depending on the choice of embedded NFC security scheme used. Bluetooth, on the other hand, can transmit many types of data over a distance of up to 100m. Out of Band (OoB) ensures secure pairing Combining the security of NFC with the open communication of Bluetooth results in numerous advantages. Bluetooth offers AES-128 encryption, which is robust enough against audio attacks and the decryption of intercepted data packets. However, security and user-friendliness can be increased if NFC comes into play; since NFC requires close proximity, there is no man-in-19
20 EMBEDDED COMPUTING // DATA COMMUNICATION Use of BLE beacons: Beacons enable localized marketing and a number of other business usage scenarios - the middle problem and prevent an undesired connection without the knowledge or permission of the user. This is done by transmitting security keys for the pairing information, called out-of-band (OoB) pairing, and works within the limited NFC transmission range. NFC pairing is extremely simple and takes place by touching or being in close proximity to two devices. Let us consider e.g. Smart meters that are read out at intervals of several weeks or months. The wireless meter interface can remain switched off until a technician places an NFC reader or an NFC-enabled mobile device in close proximity (tagging). The initial energy for activating the counter is provided via an NFC antenna. The BLE part can be in deep sleep mode the entire time in order to guarantee minimal power consumption, since the BLE IoT node does not have to check any transmission requests (advertising) if it is not needed for a longer period of time. After the credentials of the reader have been confirmed, a BLE connection can be established. Out of Band (OoB) pairing in practice Although this may sound complex at first glance, pairing and data transfer in practice are quite simple and intuitive. NFC and Bluetooth both play out their strengths. First, the mobile device is placed near the NFC-enabled device. Although it may sound complex at first glance, OoB pairing and data transfer are very simple and intuitive in practice. Heiner Tendyck, Toshiba Electronics Europe Small form factor: The TC35667FTG-based development kit measures only 17mm x 20mm. A smartphone or tablet then touches a payment terminal or an office printer, for example. In devices with Toshiba's TC35670Bluetooth LowEnergy + NFC Tag IC, the energy from the NFC antenna in the mobile device activates the permanently installed device. This then transmits its Bluetooth credentials securely via NFC. The mobile device recognizes the permanently installed device and begins the pairing request and the transmission of security keys via NFC. This eliminates the need to review and enter a string to confirm that the correct devices are being connected. The secure transmission prevents the security keys from being accidentally or maliciously intercepted by a man in the middle attack. The pairing is now complete and both devices can carry out a secure AES-128-encrypted Bluetooth communication for data transmission. An application can now be started on the mobile device depending on the format of the NFC data. Bluetooth beacons: new applications emerge The proximity detection with NFC and the subsequent secure data transmission via BLE open up new application possibilities. One of them are beacons. These are extremely energy-saving, simple devices that transmit simple data such as e.g. Send web addresses to devices (and thus to their users) in the vicinity. Beacons are suitable for numerous indoor applications, e.g. for advertising, navigation, building management and inventory control. As soon as a beacon is positioned, app users can receive localized notifications in the vicinity, provided the app is activated. Beacons are usually very energy efficient and are operated by a small button cell battery that lasts for weeks, months or even years. In retail, customers can be directed to specific products that they select on the app. Special offers can also be pointed out in this way. In a supermarket, beacons can help customers take away the most efficient way to do all of their shopping. In the business environment, goods equipped with beacons can be tracked and localized in order to increase security and ensure efficient operation (including maintenance). Marketing teams are constantly coming up with new ideas around this technology and application scenarios for beacons. In a stadium or theater, for example, beacons can guide the audience to their seats. Further application possibilities can be found in sales when offering merchandising, special offers and the processing of discounts for advertising products. These are a few examples where BLE and NFC work together to open up new possibilities. Beacons are usually unidirectional and send simple information such as an Internet address or a location. In another application, however, the beacon software and content could be updated wirelessly or via BLE (over-the-air update), triggered and secured by NFC pairing. The connection to 20
21 Engineering Leadership EMBEDDEDCOMPUTING // DATA COMMUNICATION Function overview: The SDK is a fully equipped tool based on established technology. The future has begun Tagging a beacon via NFC is much easier than pairing via Bluetooth. It is also more secure because no security information can be intercepted. Rapid development and implementation of beacon technology As with all new technologies, the appropriate hardware and software must be available in order to be able to gain market share quickly when it is introduced. One of the biggest challenges is the steep learning curve many development teams have to go through when implementing this new technique. In order to be able to bring fully functional beacons to market quickly, Toshiba offers an independent reference design based on the ultra-low power BLE IC TC35667 and the combined BLE + NFC tag IC TC35670. The reference design consists of a small (17mm x 20mm) module. It contains the TC35667FTG as well as oscillators, EEPROM, an integrated antenna and test connections with 1.27mm pin spacing. A connection for an external NFC antenna is also available (with the TC35670). When sending advertising or information, the maximum power consumption is only 5.9mA. In deep sleep mode this value drops to only 0.1μA. The average power consumption depends on the selected transmission cycle. If this happens every second, the average power consumption is around 30uA. The reference design also offers a variety of custom options. The IC can be exchanged in order to use Bluetooth 4.1 (TC35676) or Bluetooth 4.2 (TC35678) with embedded flash memory (instead of external EEPROMs) for the application. Extensive support and documentation is available in the form of circuit diagrams, parts lists, layout guidelines, Gerber files and antenna patterns. A module solution (from Panasonic Europe: PAN1760 / PAN1761) is also available. A starter kit from Toshiba supports programming and debugging based on common C ++ debuggers. Toshiba also offers a Bluetooth Software Development Kit (SDK), a complete solution that simplifies the use of Toshiba's Bluetooth LSIs and speeds time to market. This solution is available free of charge from Toshiba's developer website. It supports multiple chipsets and platforms, including host-based and stand-alone Bluetooth low-energy systems, SPPover BLE profiles and the combined BLE + NFC function. The software API supports BLE GATT server and client as well as the GAP central & peripheral function. Minimal development effort is required to configure a beacon that works with one of these standards. The developer simply sets the data format in a data array and makes a function call to configure the beacon. A C ++ standard debugging environment then takes care of the compilation and execution of the SDK code and the beacon is in operation. The integration of all available beacon standards ibeacon (Apple), AltBeacon (Radius Networks), EddystoneTM (Google) etc. is thus easily possible via Toshiba's SDK. // SG ToshibaElectronicsEurope SMARC 2.0 is the new standard for low-power computer-on-modules SMARC2.0 specification by SGeT e.v.
