STMicroelectronics’ new inertial modules enable AI training inside the sensor

Mon, Jun 20, 2022

STMicroelectronics has introduced ISM330ISN inertial sensors that contain an intelligent sensor processing unit (ISPU). The company said the power the onlife era: interacting with trained devices, with intelligence moving from “on” the edge to “in” the edge.

The ISM330ISN always-on, six-axis inertial measurement unit (IMU) for movement and position sensing uses its embedded intelligence to deliver unrivalled performance and accuracy for its size and power, claimed ST. Used in IoT and industrial applications, the IMU sets to accelerate response time and extend battery life in equipment such as condition monitors for predictive maintenance, as well as battery-operated asset trackers and industrial applications, such as robots.

The intelligence built into the ISM330ISN enables smart devices to perform advanced motion detection functions in the sensor without interaction with the external microcontroller (MCU), thus saving power at system level. ST’s approach integrates a specialised processor, the ISPU, in a small area directly on the sensor chip, optimised for machine learning applications. This enables the ISM330ISN module to have a 50 per cent smaller footprint and consume 50 per cent less power than a typical co-packaged MCU, claimed the company.

Developers can programme the ISPU using ST’s NanoEdge AI Studio. This tool is used to deploy AI applications on STM32 microcontrollers. The technology is now available for programming the ISPU, enabling users to easily generate automatically optimised machine learning libraries. Designing an anomaly detection library with AI learning capability directly inside the ISPU is possible with minimal data and just a few clicks, claimed the company, and with no specific data science skills needed.

“Intelligence formerly implemented at the network edge, in an application processor, is now moving to the deep edge, inside the sensor,” said Simone Ferri, general manager of marketing, Analogue MEMS and Sensors Group, STMicroelectronics. “Our ISM330ISN IMU heralds a new category of smart sensors, leveraging embedded AI to handle complex operations such as pattern recognition and anomaly detection with greatly increased efficiency and performance.”

The ISM330ISN has the same 3.0 x 2.5 x 0.83mm package outline as conventional inertial modules. Designers can therefore upgrade products quickly and cost-effectively with no obligation to change an established circuit board layout.

The ISM330ISN is covered by ST’s 10-year longevity programme, which provides long-term availability assurance for product designers and manufacturers.

The ISM330ISN is part of ST’s iNEMO family of IMUs. It contains a three-axis accelerometer and three-axis gyroscope with low-noise sensing performance, and an output data rate (ODR) of 6.6kHz. With the ISPU, the sensor ensures consistently high accuracy while consuming only 0.59mA in combination mode with the accelerometer and gyroscope active.

ST’s ISPU architecture, based on digital signal processing (DSP), is compact and power-efficient, with 40kbytes of RAM, and occupies just 8,000 gates on the sensor die. Performing floating-point operations with single-bit precision, ISPU is suitable for machine learning applications and binary neural networks, claimed the company.

The ISM330ISN is scheduled to enter production in the second half of 2022 and will be available from st.com or distributors. NanoEdge AI Studio enabling the creation of libraries designed for specific ISPU part numbers is available at no charge on ST.com.

ST’s ISPU and the NanoEdge.AI tools have been shortlisted for the Embedded Award at Embedded World 2022, in the Hardware and Software categories respectively (in Nuremberg, Germany, 21-23 June). ST will be exhibiting in Hall 4A-148.

Variation of SARA-R5 LTE-M works with AWS

Fri, Jun 17, 2022

A variant of the SARA-R5 LTE-M cellular module series has been introduced by u-blox to make it easier, cheaper and quicker to develop secure IoT networks with AWS (Amazon Web Services).
The SARA-R510AWS module serves a variety of applications that require reliable and secure cloud connectivity, for example asset tracking, smart farming, sensor monitoring and connected medical equipment.

Building and commercialising secure and scalable cloud-connected IoT networks that are easy to maintain over their lifetime can be challenging, said u-blox, explaining the introduction of the AWS module. In addition to requiring expertise in embedded development, networking, cryptography and cloud architecture, developers need to be proficient in handling a complex software stack. The SARA-R510AWS module offers product developers a straightforward path to secure and scalable AWS cloud services, said u-blox. This considerably reduces product development time and effort and cuts time to market. Using a stripped-down command interface, the module can connect to the AWS cloud using just two dedicated AT commands.

The SARA-R510AWS runs validated AWS IoT ExpressLink firmware which handles steps such as networking, authentication, and secure data transfer. There are also security features, including a pre-provisioned hardware-based root of trust, secure boot, and secure storage, as well as encrypted communication to and from the cloud, enabling secure over the air updates of the host processor and the module’s communication firmware.

u-blox will exhibit the SARA-R510AWS at Embedded World in Nuremberg, Germany from 21 to 23 June 2022, on the AWS stand in Hall 4-548.

u-blox specialises in positioning and wireless communication in automotive, industrial and consumer markets. Its services and products let people, vehicles, and machines determine their precise position and communicate wirelessly over cellular and short range networks. The company has a broad portfolio of chips, modules, and secure data services and connectivity.

Sitara AM62 processors expand edge AI while cutting the power budget

Tue, Jun 07, 2022

Sitara AM62 processors have been released by Texas Instruments. The company said that they help expand edge artificial intelligence (AI) processing and the low power design enables support for dual-screen displays and small size human machine interface (HMI) applications.

According to Texas Instruments (TI), the next generation of HMI will bring new ways of interacting with machines, such as enabling gesture recognition to give commands in a noisy factory environment or enabling the control of machines by phones or tablets with a wireless connection. The AM62 processors bring analytics to edge devices at low power, including suspend states as low as 7mW. There is also no need to design for thermal considerations, said TI, which can give engineers flexibility to deploy new capabilities in size-constrained applications or industrial environments. Adding edge AI features to HMI applications, including machine vision, analytics and predictive maintenance, can advance HMI beyond a mere interface to enable human-machine interaction.

The AM62 processor starts at less than $5.00 to bring low-cost analytics to HMI devices with basic camera-based image processing and edge AI functions, such as detecting and recognising objects, said TI. AM62 processors also enable dual-screen, full HD displays and support for multiple operating systems, including Mainline Linux and Android operating systems. AM62 processors also support both wired and wireless connectivity interfaces.

Additionally, the AM62 processors can reduce power consumption in industrial applications by as much as 50 per cent compared to competing devices, said TI. They can thus enable an application powered by AA batteries to remain on for over 1,000 hours. This is possible, said TI, due to a simplified power architecture. The device features only two dedicated power rails and five power modes. Deep sleep mode at less than 5mW enables longer battery life, while an active power of less than 1.5W is made possible by a core voltage of 0.75V. Reducing system power consumption extends battery life and helps engineers meet design requirements for handheld or size-constrained devices. Achieving optimal power performance is further simplified with the new TPS65219, a companion PMIC specifically designed to meet AM62 processor power supply requirements, said TI.

There is a wide range of tools and resources for AM62 processors including multiple open-source software such as Mainline Linux, to simplify the application development process and help accelerate time to market. A hardware ecosystem includes a third-party evaluation module.

The AM625 and AM623 processors are now available in a 13 x 13mm, 425-pin ALW package. It is available directly from TI and authorised distributors.

TI will showcase the AM62 processors and demonstrate system-level solutions for edge AI and electric vehicle charging HMI applications in at Embedded World in Nuremberg, Germany (21 to 23 June 2022) at its stand in Hall 3A #215.
