3.5″ Board Designed Rugged Environments

AAEON has launched the GENE-SKU6 W1, a 3.5-inch subcompact board with the specifications needed to handle harsh, unstable conditions. When hardware is used for outdoor, factory automation, or in-vehicle applications, you can’t always be sure that its DC input will remain stable. Because businesses can’t afford for their systems to shut down, they need computers that can withstand power fluctuations and keep on running. With that in mind, the GENE-SKU6 W1 has a DC input range of 9 to  36 VDC, so it takes power drops and spikes in its stride and continues operating.

pgal_160922_8bg2utThis rugged subcompact board also has a WiTAS 1 wide-temperature rating, meaning it’s guaranteed to run smoothly in environments as cold as -20°C and as hot as 70°C. This capability is achieved through intelligent design, low-power components and an effective heatsink. Those design features enable the GENE-SKU6 W1 to function as a reliable, fanless solution.

The board’s features include support for 4K resolution and independent DP, DVI, and LVDS display outputs. It has Mini-card and mSATA slots, four USB 3.0 and two USB 2.0 ports, four COM ports and an additional BIO interface enabling board-to-board connection.

Op Amp Features Ultra-High Precision

Texas Instruments (TI) has introduced an op amp that combines ultra-high precision with low supply current. The LPV821 zero-drift, nanopower op amp enables engineers to attain the highest DC precision, while consuming 60% less power than competitive zero-drift devices, according to TI. The LPV821 is designed for use in precision applications such as wireless sensing nodes, home and factory automation equipment, and portable electronics.

LS-First-Page

The LPV821 is a single-channel, nanopower, zero-drift operational amplifier for “Always ON” sensing applications in wireless and wired equipment where low input offset is required. With the combination of low initial offset, low offset drift, and 8 kHz of bandwidth from 650 nA of quiescent current, the LPV821 is the industry’s lowest power zero-drift amplifier that can be used for end equipment that monitor current consumption, temperature, gas, or strain gauges.

The LPV821 zero-drift op amp uses a proprietary auto-calibration technique to simultaneously provide low offset voltage (10 μV, maximum) and minimal drift over time and temperature. In addition to having low offset and ultra-low quiescent current, the LPV821 amplifier has pico-amp bias currents which reduce errors commonly introduced in applications monitoring sensors with high output impedance and amplifier configurations with megaohm feedback resistors.

Engineers can pair the LPV821 op amp with the TLV3691 nanopower comparator or ADS7142 nanopower analog-to-digital converter (ADC) to program a threshold that will automatically wake up a microcontroller (MCU) such as the CC1310 SimpleLink Sub-1 GHz MCU, further reducing system power consumption.

Designers can download the TINA-TI SPICE model to simulate their designs and predict circuit behavior when using the LPV821 op amp. Engineers can also jump-start gas-sensing system designs using the LPV821 op amp with the Always-On Low-Power Gas Sensing with 10+ Year Coin Cell Battery Life Reference Design and Micropower Electrochemical Gas Sensor Amplifier Reference Design.

Pre-production samples of the LPV821 op amp are now available through the TI store and authorized distributors in a 5-pin small-outline transistor (SOT-23) package. Pricing starts at $0.80 in 1,000-unit quantities.

LF Resonator Filter

Frequency Measurements

In Ed’s November article he described how an Arduino-based tester automatically measures a resonator’s frequency response to produce data defining its electrical parameters. Here, he examines the results of those measurements and delves into variable series capacitance as measurement aid.

By Ed Nisley

Quartz resonators—also known as “crystals”—normally set the frequency of a clock oscillator circuit to a precise value, but they can also become filters passing analog signals. Because resonators have an extremely high Q, the filters have a very narrow bandwidth and require precise center-frequency tuning. The Arduino-based tester I described in my November 2017 article (Circuit Cellar 328) automatically measures a resonator’s frequency response to produce the data defining its electrical parameters for use as either an ordinary oscillator or a filter isolating the 60 kHz WWVB signal from the surrounding RF clutter.

In this article, I’ll describe the results of those measurements, explain a tester modification to measure the resonator’s response with a variable series capacitance, then show what a resonator filter does to the 60 kHz WWVB preamplifier’s response.

Resonator Frequencies

Over the course of a few months, I bought two lots of 25 quartz tuning fork resonators from eBay, measured all 50 resonators, then converted the data into the histograms in Figure 1. The blue bars show the series resonant frequencies form a reasonably smooth distribution around 59996.1 Hz, 4 Hz below the nominal 60 kHz. A 24 pF series capacitance shifted the resonances upward by 1.7 Hz to produce a similar distribution of the red bars around 59997.8 Hz, showing the resonators behave as expected.

FIGURE 1
The blue bars summarize the series
resonant frequencies of fifty tuning
fork resonators. Inserting a 24-pF
series capacitor shifts the resonant
frequencies upward by about 1.7 Hz.

In contrast, refer to the magnetic sensitivity histograms of the Hall effect sensors in my May 2015 article (Circuit Cellar 298). Those eBay parts apparently came from production-line reject bins, because I got only the parts with responses far from their nominal value. My experience suggests you should not expect cheap electronic parts bought from eBay to meet their specifications and you must measure what you get.

The resonator responses cluster below 60.000 kHz, because they’re intended to be built into oscillator circuits with specific values of external capacitances to set the final frequency. For example, most digital oscillators use a Pierce topology with the resonator connected as a feedback element for a CMOS inverter biased into its linear range and a capacitor from each resonator lead to ground. Those oscillators operate near the resonator’s parallel resonance frequency, with the final frequency pulled slightly higher by the load capacitors. …

Wearables Drive Demand for Extreme Low Power Solutions

Wearables-Issue-329Wearable devices put extreme demands on the embedded electronics that make them work. Devices spanning across the consumer, fitness and medical markets all need a mix of low-power, low-cost and high-speed processing.


 

 

MCUs & Analog ICs Meet Needs

By Jeff Child, Editor-in-Chief

Designers of new wearable, connected devices are struggling to extend battery life for next-generation products, while at the same time increasing functionality and performance in smaller form factors. These devices include a variety of products such as smartwatches, physical activity monitors, heart rate monitors, smart headphones and more. The microcontrollers embedded in these devices must blend extreme low power with high integration. Meanwhile, analog and power solutions for wearables must likewise be highly integrated while serving up low quiescent currents.

Modern wearable electronic devices all share some common requirements. They have an extremely low budget for power consumption,. They tend not to be suited for replaceable batteries and therefore must be rechargeable. They also usually require some kind of wireless connectivity. To meet those needs chip vendors—primarily from the microcontroller and analog markets—keep advancing solutions that consume extremely low levels of power and manage that power. This technology vendors are tasked to keep up with a wearable device market that IDC forecasts will experience a compound annual growth rate (CAGR) of 18.4% in 2020.

MCU and BLE Combo

Following all those trends at once is Cypress Semiconductor’s PSoC 6 BLE. In September the company made its public release of the PSoC 6 BLE Pioneer Kit and PSoC Creator Integrated Design Environment (IDE) software version 4.2 that enable designers to begin developing with the PSoC 6. The PSoC 6 BLE is has built-in Bluetooth Low Energy (BLE) wireless connectivity and integrated hardware-based security.

According to Cypress, the company had more than 2,500 embedded engineer customers registering for the PSoC 6 BLE early adopter program in just a few months. Early adopters are using the flexible dual-core architecture of PSoC 6, using the ARM Cortex-M4 core as a host processor and the Cortex-M0+ core to manage peripheral functions such as capacitive sensing, BLE connectivity and sensor aggregation. Early adopter applications include wearables, personal medical devices, wireless speakers and more. Designers are also using the built-in security features in PSoC 6 to help guard against unwanted access to data.

The PSoC BLE Pioneer Kit features a PSoC 63 MCU with BLE connectivity (Photo 1). The kit enables development of modern touch and gesture-based interfaces that are robust and reliable with a linear slider, touch buttons and proximity sensors based on the latest generation of Cypress’ CapSense capacitive-sensing technology. Designers can also use the board to add USB Power Delivery (PD) with its Cypress EZ-PD CCG3 USB-C controller. The development kit also includes a 2.7-inch E-ink Display Shield add-on board (CY8CKIT-028-EPD) with thermistor, digital mic and 9-axes motion sensor.

Deep Sleep Current Levels

Extreme low power was also the theme behind Microchip Technology’s PIC32MX1/2 XLP family that the company announced in June. The 33-bit PIC32MX1/2 XLP offers current PIC32MX system developers an easy migration path to achieve higher performance at much lower power. It enables both increased functions and longer battery life in portable applications. According to Microchip, the new MCU family increases performance in small pin-count devices with little code rework for existing customers.

Microchip’s XLP technology is designed for wearable technology, wireless sensor networks and other smart connected devices and offers low current operating modes for Run and Sleep, where extreme low-power applications spend 90% to 99% of their time. XLP technology will enable Sleep and Deep Sleep shutdown states on the PIC32MX1/2 XLP devices, enabling Deep Sleep currents down to 673 nA. The devices offer over 40% more performance than the existing PIC32MX1/2 portfolio while reducing average currents by 50%. Figure 1 shows an XLP MCU used in a health/fitness wearable application.

WearablesFigure1

Figure 1 Shown here is a Microchip XLP MCU used in a health and fitness wearable application.

The PIC32MX1/2 XLP family is available in a range of memory configurations with 128/256 kB flash and 32/64 kB of RAM in packages ranging from 28- to 44-pins. They also include a diverse set of peripherals at a low cost including I2S for digital audio, 116 DMIPS performance for executing audio and advanced control applications, a 10-bit, 1 Msps, 13-channel ADC and serial communications peripherals. The PIC32MX2 series also supports USB-device, host and OTG functionality.

In addition to the hardware peripheral features, the series is supported by Microchip’s MPLAB Harmony Software Development Framework, which simplifies development cycles by integrating the license, resale and support of Microchip and third-party middleware, drivers, libraries and RTOSes. Specifically, Microchip’s readily available software packages such as Bluetooth audio development suites, audio equalizer filter libraries, decoders (including AAC, MP3, SBC), sample rate conversion libraries and USB stacks will reduce the development time of wearable device applications.

Transactions with Wearables

Among the new features of some wearable devices is the ability to do contactless transactions. Today’s consumers have become quite comfortable with making secure transactions using their smart devices. As a result, traditional card manufacturers want to extend their offerings into contactless wearable products for uses such as payments, ticketing and access control. These can be difficult to implement within tight size and cost constraints, because conventional separate NFC-radio and security chips demand extra space and complicate design. In addition, wearable form factors tend to need small antennas that can restrict communication performance.

Supporting those capabilities in wearables, ST Microelectronics in October unveiled its technology for easy and secure contactless transactions using electronic wristbands or fashionwear like watches or jewelry. The ST53G System-in-Package solution combines the company’s expertise in Near Field Communication (NFC) and secure-transaction chips. ST’s new ST53G System-in-Package combines a miniaturized and enhanced NFC radio with a secure banking chip in one compact 4 mm x 4 mm module (Figure 2). The company’s proprietary boosted-NFC technology enables wearables with small antennas to deliver a great user experience when interacting with card readers over typical contactless distances.

Figure 2 ST’s ST53G System-in-Package combines a miniaturized and enhanced NFC radio with a secure banking chip in one compact 4 mm x 4 mm module.

Figure 2
ST’s ST53G System-in-Package combines a miniaturized and enhanced NFC radio with a secure banking chip in one compact 4 mm x 4 mm module.

The simplicity of this all-in-one module helps card enables embedded developers to quickly design functional and attractive wearables that can range from fashion items to one-time devices like event wristbands. ST offers an extensive development ecosystem, including radio-tuning tools and pre-defined antenna configurations. The ST53G meets all relevant card-industry standards, including EMVCo compliance, ISO/IEC-14443 NFC card emulation, and MIFARE ticketing specifications. The ST53G can host ready-to-use STPay smartcard operating systems and optional VISA/ Mastercard/JCB-certified banking applications pre-loaded on the secure microcontroller.

Embedded Security for Wearables

The secure banking chip contained in the ST53G System-in-Package leverages ST’s proven ST31G480 secure microcontroller that is based on the ARM SC000 SecurCore processor. It features a secure architecture with a NESCRYPT coprocessor for public-key cryptography and hardware accelerators for algorithms like AES and triple-DES. Extensive anti-tamper protection including an active shield, environmental monitoring, a unique serial number for each die and protection against numerous other attacks are also built-in. These features complement software-based security running on the SC000 core to ensure the strongest possible protection for users’ credentials.

The contactless IC is the STS3922 RF booster, which uses active-load modulation (ALM) to maximize transaction range and omnidirectional radio performance in card-emulation mode. This enables wearable devices to be easy to use—with equal or better device-to-reader positioning tolerance than conventional contactless smartcards—even though a smaller antenna is used. Using ST53G contributes to final device cost optimization because small antennas can be etched onto the PCB at almost zero additional cost. In some cases, a challenging metallic case can itself be used as part of the RF antenna.

Automatic power and gain control, configurable sensitivity, and configurable signal/reader-field phase difference ensure consistent communication over all ranges. These enhance smooth interoperability with different types of readers and terminals including various transportation ticketing systems. The STS3922 has a dedicated secure-MCU wake-up output. That feature enables the ST53G System-in-Package to maximize battery life by powering down when not in use.

Power Regulation for Wearables

Designing today’s wearable devices requires not just low power on the MCU side. They also require sophisticated analog IC solutions that help regulate power and extend battery life as much as possible. Along those lines, Maxim Integrated in March announced its the MAX17222 nanoPower boost regulator with what the company claims is the industry’s highest efficiency and lowest quiescent current (IQ) of only 300 nA (Figure 3). The 0.4V to 5.5V input, 1.8V to 5V output boost regulator with 500 mA input current limit reduces solution size by up to 50% compared to similar products and offers 95% peak efficiency to minimize heat dissipation.

Figure 3 The MAX17222 boost regulator offers a low quiescent current of 300 nA, 0.4V to 5.5V input, 1.8V to 5V output and 500 mA input current limit.

Figure 3
The MAX17222 boost regulator offers a low quiescent current of 300 nA, 0.4V to 5.5V input, 1.8V to 5V output and 500 mA input current limit.

Aside from very low quiescent current, the MAX17222 also minimizes heat dissipation and shutdown current. In True Shutdown mode, the minuscule current draw of 0.5 nA virtually stops battery drain to provide the longest battery life and eliminate the need for external disconnect switches. The MAX17222 is internally compensated and requires only a single configuration resistor and small output filter for a full power solution. For ease of use, the boost regulator comes in tiny, density-optimized 0.88 mm x 1.4 mm 6-bump WLP and 2 mm x 2 mm 6-pin standard µDFN packages. It operates over a -40°C to +85°C temperature range.

Health monitoring wearable devices have their own particular analog design challenges. Targeting such needs, Analog Devices offers a low power, next-generation biopotential analog front end (AFE) which enables smaller, lighter and less obtrusive cardiac monitoring devices with longer battery life. The AD8233 AFE is a fully integrated, single-lead electrocardiogram (ECG) front end designed in one compact, easy-to-use component. Typically, developers need to design ECG front ends from individual components, which can add incremental cost and design time.

Health Monitoring Solution

The highly integrated, out-of-the-box AD8233 AFE eliminates these unnecessary costs and extra time, helping developers get products to market more quickly. Additionally, the device’s 2.0 mm × 1.7 mm size enables the design of wearable health devices that are smaller, lighter and easier to wear. Bulky, heavy and obtrusive monitors can be unpleasant for patients to wear and may even interfere with their everyday lives. Longer battery life is another crucial attribute for cardiac monitors and is vital to ensure continuous monitoring that provides accurate data without the interruption of a recharge or battery replacement. The AD8233 AFE’s low microamp-range power consumption results in greatly extended battery life.

Along with its small size, the single-supply (1.7 V to 3.5 V) AD8233 features extremely low quiescent current of 50 μA (typical); lead on/off detection even while in shutdown mode (less than 1 μA); and 80-dB common-mode rejection ratio (DC to 60 Hz). Electrical noise, a critical specification for cardiac-monitoring devices, is below 10 μV from 0.5 to 40 Hz. The AD8233 also allows for highly flexible filter configurations which are essential to consistent, confident operation in an inherently harsh electrical environment under a range of use cases. These configuarations include a two-pole adjustable high-pass filter, a three-pole adjustable low-pass filter with adjustable gain and an RFI filter. For ease-of-use and flexibility, it also includes an integrated right leg drive (RLD) amplifier with shutdown plus an uncommitted op amp. Analog Devices also offers an evaluation board, reference design, web based filter design tool and Spice model to facilitate design-in and speed time to market.

The AD8233CB-EBZ evaluation board contains an AD8233 heart rate monitor (HRM) front end conveniently mounted with the necessary components for initial evaluation in fitness applications (Photo 2). Inputs, outputs, supplies and leads off detection terminals are routed to test pins to simplify connectivity. Switches and jumpers are available for setting the input bias voltage, shutdown (SDN), right leg drive shutdown (RLD SDN), fast restore (FR) and AC/DC leads off detection mode. The AD8233CB-EBZ evaluation board is a 4-layer board with components mounted on the primary side only. Rubber feet are available on the secondary side for mechanical stability. The layout diagrams are provided as a visual aid and reference design.

Wireless Connectivity

Seamless wireless connectivity has pretty much become a given for today’s wearable devices. With that in mind, Cypress Semiconductor in September announced a new combo solution that delivers ultra-low power Wi-Fi and Bluetooth connectivity to extend battery life for wearables and portable audio applications. The new Cypress CYW43012 solution prolongs battery life by leveraging 28 nm process technology to cut power consumption up to 70% in receive mode and up to 80% in sleep mode when compared to current solutions. The solution is IEEE 802.11a/b/g/n-compliant and 802.11ac-friendly, meaning it is interoperable with 802.11ac access points using standard modes. This enables it to offer higher throughput and better energy efficiency, along with the enhanced security and coverage of 802.11ac Wi-Fi networks.

The CYW43012 combo chip’s advanced coexistence engine enables optimal combined performance for dual-band 2.4- and 5-GHz Wi-Fi and dual-mode Bluetooth/BLE 5.0 applications simultaneously. The CYW43012 solution is supported in Cypress’ all-inclusive, turnkey, WICED Studio IoT development platform, which streamlines the integration of wireless technologies for developers. According to Cypress, battery life is a key differentiator for connected devices like wearables. Users demand a great connected experience for longer without having to recharge.

The Cypress WICED Studio IoT development platform features an integrated and interoperable wireless software development kit (SDK). The SDK includes broadly deployed and rigorously tested Wi-Fi and Bluetooth protocol stacks, as well as simplified application programming interfaces that free developers from needing to learn complex wireless technologies. In line with the IoT trend toward dual-mode connectivity, the SDK supports Cypress’ Wi-Fi and Bluetooth combination solutions and its Bluetooth and Bluetooth Low Energy devices. The SDK enables cloud connectivity in minutes with its libraries that integrate popular cloud services such as Amazon Web Services, IBM Bluemix, Alibaba Cloud and Microsoft Azure, along with services from private cloud partners. WICED also supports iCloud remote access for Wi-Fi-based accessories that support Apple HomeKit, which enables hub-independent platforms that connect directly to Siri voice control and the Apple Home app remotely.

Cypress’ WICED Studio connectivity suite actually is MCU-agnostic and provides support for a variety of third-party MCUs to address the needs of complex IoT applications. The platform also enables cost-efficient solutions for simple IoT applications by integrating MCU functionality into the connectivity device. Wi-Fi and Bluetooth protocol stacks can run transparently on a host MCU or in embedded mode, allowing for architectures with common firmware.

As consumers push for more capabilities in their wearable products, they won’t tolerate any reduction in battery life. Along the way, wireless connectivity and embedded security will have to be supported. These conflicting trends will continue to challenge MCU and analog IC vendors to come up with more integrated solutions at ever lower power consumption levels.

Dotdot Spec to Run on Thread’s IP Network

The Zigbee Alliance and Thread Group have announced the availability of the Dotdot specification over Thread’s IP network. This enables developers to confidently use an established, open and interoperable IoT language over a low-power wireless IP network. This is expected to help unify the fragmented connected device industry and unlock new markets.

Dotdot is the Zigbee Alliance’s universal language for the IoT, making it possible for smart objects to work together on any network. Thread is the Thread Group’s open, IPv6-based, low-power, secure and future-proof mesh networking technology for IoT products. These two organizations have come together to deliver a mature, scalable solution for IoT interoperability that isn’t confined to single-vendor ecosystems or technologies.

Dotdot-over-Thread-no-sub-01The early Internet faced the same challenges as today’s IoT. Currently, connected devices can struggle to deliver a seamless experience because they speak different languages (or in technical terms, use different “application layers”). For the internet, the industry solved this problem with open, universal protocols over IP. Dotdot’s common device language over Thread’s IP network extends this same proven approach to the Internet of Things. With Dotdot over Thread, product and platform vendors can ensure the high-quality, interoperable user experiences needed to drive growth, while IP allows vendors to maintain a direct connection to their device.

It’s important to note that Dotdot over Thread is not another new standard. Dotdot enables the open, mature, and already widely adopted application layer at the heart of Zigbee to work across Thread’s IP network. It uses the same network technology fundamental to the internet. For product managers, new standards represent risk.

Fanless SBC Targets Industrial IoT

Technologic Systems is now shipping its newest single board computer, the TS-7553-V2. The board is developed around the NXP i.MX6 UltraLite, a high performance  processor family featuring an advanced implementation of a single ARM Cortex-A7 core, which operates at speeds up to 696 MHz. While able to support a wide range of embedded applications, the TS-7553-V2 was specifically designed to target the industrial Internet of Things (IIoT) sector.

ts-7553-v2The TS-7553-V2 was designed with connectivity in mind. An on-board Xbee interface, capable of supporting Xbee or NimbleLink, provides a simple path to adding a variety of Wireless interfaces. An Xbee radio can be used to link in with a local 2.4GHz or sub 1 GHz mesh networks, allowing for gateway or node deployments. Either Digi or NimbleLink offer cellular radios for this socket, providing cellular connectivity for applications such as remote equipment monitoring and control. There is also the option for a cellular modem via daughter card. This allows transmission of serial data via TCP, UDP or SMS over the cellular network. The TS-7553-V2 also includes an on board WiFi b/g/n and Bluetooth 4.0 option, providing even more connectivity.

Further radio expansion can be accomplished with the two internal USB interfaces (one on a standard USB Type A connector, and the second on simple pin headers). The USB interfaces enable support for multiple proprietary networks via a dongle or USB connected device. This provides the opportunity to run mesh, LoRa, ZigBee, automotive WiFi or other protocols with the TS-7553-v2 . All of these radio options combined with the on board 10/100Base-T Ethernet create the opportunity to communicate seamlessly with up to 5 different networks simultaneously from a single point.

The TS-75553-V2 supports standard interfaces including:

  •     10/100 Ethernet
  •     TTL UART
  •     4 USB ports (3 host interfaces and, 1 device)
  •     3 RS-232 Serial/COM ports
  •     RS-485 port
  •     CAN bus
  •     Up to 5 GPIO

A Nine-Axis Micro-Electro-Mechanical System (MEMS) motion tracking device containing a gyroscope, accelerometer and compass are optional on-board in for asset management, fleet management and other applications which would require sensing motion or vibration in the environment.

A low cost monochrome 128x64px LCD with 4 button keypad is available for Human Machine Interface (HMI) applications.  The keypad offers intuitive operation using 4 tactile function keys and the LCD is ideal for simple visualization tasks, even in harsh environments.  If HMI is not a consideration compact, lightweight, rugged enclosures are available to contain your gateway in a secure fanless enclosure. Both enclosures are DIN mountable.

Technologic Systems has taken the lead in combating read/write errors to memory that can prove fatal to Operating Systems. TS-SILO is an optional feature which will provide up to 30 seconds of reserve power in the event of a power failure. This precious extra time gives the board time to gracefully power down and ensures file system integrity. Additionally, for heavy data logging applications The TS-7553-V2 is the first SBC from Technologic Systems to include Ferroelectric RAM (FeRAM or FRAM). FeRAM advantages over flash include: lower power usage, faster write performance and a much greater maximum read/write endurance, allowing a user to keep running data logs without prematurely wearing out their flash memory. Combined these two features provide you with insurance from abrupt power loss, read/write errors and startup difficulties.

Applications with strict low power requirements will appreciate the work that’s been done to reduce power consumption to less than 2 W in typical conditions and a 9 mW sleep mode. Power over Ethernet (PoE) is supported via a daughter card, if desired.

Development can begin out-of-the-box with pre-installed Linux and utilities for controlling DIO, UARTS, CAN bus, and more. A complete board support package is provided, as well as access to our software repository and online support. Third party application support can be provided via the Technologic Systems’ Partner Network.
