Version 3 NanoEdge AI Studio offers streamlined solution

The shift of artificial intelligence (AI) capabilities from the cloud to the edge has given rise to this new version of NanoEdge AI Studio from STMicroelectronics to help simplify the creation of machine learning, anomaly learning, detection and classification on any STM32 microcontroller. This new release also includes prediction capabilities such as regression and outliers libraries. The tool, says the company, makes it easier for users to integrate such machine-learning capabilities quickly, easily and cost-effectively into their equipment. It emphasises that no data-science expertise is needed. There is improved support for anomaly detection, which ST says is particularly useful for predictive maintenance to anticipate wear-and-tear phenomena or to better deal with equipment obsolescence.

Adding native support for all STM32 development boards, ST has also eliminated the need to write code for its industrial-grade sensors with new high-speed data acquisition and management capabilities.

Regression algorithms have been added to extrapolate data and predict future data patterns for energy management or forecasting remaining life of equipment. 

Applications include connected devices, household appliances and industrial automation.

Steve Peguet, scientific director, innovation department of Alten Group, an international technology consulting and engineering company, said: “We had the opportunity to use NanoEdge AI Studio with one of our major aerospace customers. For machine drilling during the manufacture of expensive parts, where a worn drill-bit or the slightest anomaly can have significant consequences, Alten used NanoEdge AI Studio to integrate Machine-Learning algorithms into the drilling equipment. The solution tested on a production line was so effective that Alten has launched a practice around this technology to support its customers and to industrialise these first results to deploy a disruptive solution of drilling tools prescriptive maintenance in their factories.”

Deepak Arora, president and chief executive officer of Wearable Technologies Inc, said: “To protect our loved ones so that they can have a healthy and fulfilling life, NanoEdge AI is empowering us to reduce the machine-learning development time for our next-generation personal-safety devices. AI running at the edge on our devices will allow us to make informed decisions promptly with higher accuracy and reduced false-positives.”

αMOS5 super junction MOSFET series for high-efficiency and high-density needs 

Alpha and Omega Semiconductor has announced the 600V low ohmic and fast body diode αMOS5 super junction MOSFET series. αMOS5 is AOS’s latest generation of high-voltage MOSFET, designed to meet the high-efficiency and high-density needs for quick charger, adapter, PC power, server, industrial power, telecom and hyperscale datacentre applications.

The AOK040A60 is a 600V 40m-Ohm aMOS5 low ohmic device with the industry-standard TO-247 package tailored to address the thermal challenges of high-power AC/DC, DC/DC and Inverter stages. 

As the EU ERP Lot9 regulation pushes the efficiency of single power supply units to titanium level, AOS aMOS5 600V low ohmic family offers a solution for single, interleaved, dual boost, totem-pole, and Vienna PFCs, as well as other hard-switching topologies. The 40mOhm product, followed by the upcoming 31mOhm, 65mOhm, and 80mOhm products, aims to provide customers with multiple choices to deal with different power ratings and efficiency requirements. The optimised capacitance of AOK040A60 offers hard and soft switching performances, with fast turn-on/turn-off behaviours while avoiding the risks of self-turn-on or shoot-through.

The AOK042A60FD is a 600V 42mOhm fast body diode device, designed to handle the repetitive hard commutation scenario, where the MOSFETs freewheeling body diode is reversely recovered in half-bridge or full-bridge topologies. The aMOS5 600V FRD solution is expected to further increase the system reliability as a solution for HB/FB topologies where hard switching happens during abnormal operations, such as short-circuit or start-up transients. The low Qrr of AOK042A60FD is expected to help to significantly reduce the losses during reverse recovery. 

Besides server and telecom power supplies, the AOK040A60, AOK042A60FD and their derivatives will also target the demanding EV DC charging and solar inverter applications.   

The 600V aMOS5 family will be expanded, including more low-ohmic and FRD products arriving early next year. As with most of the aMOS5 products, these new devices will also be made in 300mm facilities, with the intention of providing better supply elasticity during the global power semiconductor shortages.

People counting keeps the workplace safe

For people detection and counting in indoor spaces, such as office space and municipal areas, Analog Devices has developed the EagleEye ADSW4000 which uses the PeopleCount algorithm.

It is the first in a series of application-level software algorithms forming part of the ADI EagleEye platform that includes a hardware subsystem based on ADI’s Blackfin embedded DSP and a set of application-level software building blocks enabling users to quickly develop their own people counting system. The ADSW4000 algorithm provides system edge node analytics to allow intelligent insight into use of space, and how people move safely within that space with distance monitoring. It is also useful to gather intelligence on the energy efficiency of spaces within ‘smart’ buildings. 

The EagleEye counts people in indoor areas, based on the x and y co-ordinates of a person’s location. It uses zoned performance, enabling multiple areas for wider coverage and edge processing. The metadata is output over UART and no captured images are transmitted. 

EagleEye can solve workspace needs and maximise worker wellbeing and productivity, says ADI. For maximum coverage area applications, accuracy of 80 per cent can be achieved in a 5m radius.

The Eval-ADSW4000KTZ evaluation kit with embedded ADSW4000 algorithm and cloud dashboard access is available now. 

Analog Devices offers a suite of analogue and mixed signal, power management, radio frequency (RF), and digital and sensor technologies for customers in the industrial, communications, automotive, and consumer markets.

Versatile automotive touchscreen controller includes functional safety support

Multiple communication options, ISO 26262 functional safety support and flexible RF emission control are offered in the maXTouch touchscreen controller, says Microchip Technology.

According to the company, it allows automotive designers to satisfy various aspect ratios for touch displays in cars and, in response to requests by OEMs,  includes additional functional safety support.

The MXT1296M1T can reconfigure its driving and receiving touch channels to match the exact screen format, from 1:1 to 5:1 aspect ratio, i.e., including the popular 8:3 automotive aspect ratio. This allows the customer to efficiently use the number of touch channels available, without needing a larger, more expensive touch controller. Customers can save additional development and validation time, as well as resources, by reusing a common PCB design to support different touch sensor aspect ratios. The MXT1296M1T is believed to be an industry first in that it enables the sensor channel reconfiguration by parameters. Settings do not require firmware modification, which reduced the design risk and also the time to market.

Clayton Pillion director of the human machine interface (HMI) business unit at Microchip Technology, observed: “Products with enhanced diagnostic features are a significant advantage to customers who are designing with unique features and increasing ISO 26262 functional safety requirements in mind”.

The MXT1296M1T maXTouch touchscreen controller offers two communication interfaces operating simultaneously, which allow a bridgeless connection to the back channel of the LVDS video link for touch information and a connection to a local microcontroller. The bridgeless topology reduces touch latency to improve the user experience. It also guarantees compatibility with the maXTouch software driver, available for all major automotive operating systems, including Linux, Android and QNX. 

When connected to an appropriate local microcontroller, the second interface offers a number of benefits. Firstly, it offers a redundancy link to the head unit through a CAN bus or 10BASE-T1S automotive Ethernet link for increased functional safety at the system level. There is also local access and control of the maXTouch touchscreen controller’s features, for example, capacitive keys report, live touch sensor diagnostics and raw data for external and custom post-processing. 

Finally, there is over the air (OTA) and secure firmware update capability using Microchip’s TrustAnchor100 companion chip

The MXT1296M1T embeds various functional safety features to constantly check the integrity of the touch controller operation, as well as that of the connected touch sensors. The failure modes effects and diagnostic analysis (FMEDA) and functional safety manual support the customer in designing, building and certifying a system for Automotive Safety Integrity Level B (ASIL-B) applications to the ISO 26262 standard.

The MXT1296M1T allows for high resolution transmit waveform control to lower RF emissions and avoid interference with the car radio or RFID systems. As screen sizes  increase in cars, RF emissions generated by the projected capacitive touch technology are growing. (Emission limits vary in amplitude, frequency and bandwidth for each major car manufacturer.) The MXT1296M1T uses a dedicated on-chip 64-level DAC to accurately shape the waveform of the transmitting lines. As a result, designers can precisely control the frequency response and optimise the harmonic emissions to meet specific OEM-defined limits.

The MXT1296M1T configuration and tuning is supported by the latest release of maXTouch Studio integrated development environment (IDE). Microchip also offers the 

ATEVK-MXT1296M1T-A evaluation kit for order. This includes a development board with USB bridge, 12.3-inch / 8:3 format / 1.1mm OGS (one glass solution) touch panel, and touch key add-on boards for mutual and self-capacitance. 

There is also the ATMXT1296M1T-I2C-PCB development board for connection to a customer’s touch sensor

The MXT1296M1T is now available in volume production. ISO 26262 FMEDA and Functional Safety Manual will be available for purchase Q1, 2022.
