Renesas has launched the RX13T Group of 32-bit MCUs to enable inverter control of compact motors such as fans or pumps in consumer and industrial applications that previously controlled motor operation through on-off switching. This includes factory equipment where energy efficiency is a priority such as water discharge, supply pumps, or cooling fans for data sensor servers; and cordless, battery-powered ...

The Renesas Solution Starter Kit (RSSK) for developers working with the 32-bit RX23E-A MCU claims to have one of the most accurate analogue front ends (AFE) in the industry. The kit ybrings together hardware, software, and tools optimized for evaluating the MCU’s high-precision 24-bit delta-sigma (ΔΣ) A/D converter with industry-leading accuracy (0.1% is possible through the AFE). The RSSK enables ...

STMicroelectronics is aiming at automotive gateways that link car electronics to the cloud with an evaluation kit built around secured chips. Called SGP-TC-EVK ‘smart gateway platform’, potential use-cases include over-the-air (OTA) management, firewall, Ethernet packet inspection, secure CAN-to-CAN data routing, secure CAN-to-Ethernet data routing, body control management, intrusion detection and predictive maintenance. On-board M.2 and Mini PCIe expansion connectors are provided to ...

Toshiba has revealed its Arm Cortex-M microcontroller plans, announcing 200MHz (254 DMIPS) 40nm parts “dissipating approximately 30% lower dynamic power compared to the existing* 65nm devices”, it said, and 130nm parts with SONOS memory. The family is split into two device classes: TXZxA+ (A for ‘advanced’) in 40nm with either an Arm Cortex-M3 or a Cortex-M4 with floating point unit (FPU). TXZxE+ (E for ‘entry’) in 130nm CMOS with either ...

With the design of secured IoT products in mind, Microchip has announced range of cloud agnostic embedded development products that connect through Wi-Fi, Bluetooth or narrow-band 5G. “From the smallest PIC and AVR MCUs for sensors and actuators, to 32bit MCU and MPU gateways for edge computing, the company is making it possible for developers to connect to any major ...

Mouser Electronics is now stocking STM32L5 low-power microcontrollers from STMicroelectronics. The device is based on a Cortex-M33 core with Trustzone hardware-based security. Their security architecture features the Arm v8-M main extension. The M33 core with floating point unit also implements a full set of DSP (digital signal processing) instructions and a memory protection unit (MPU) that enhances application security. Additionally, ...

Menta and Secure-IC are to add cryptographic features to FPGA intellectual property (IP). Under the agreement, announced at Embedded World in Nuremberg, the companies will deliver Menta eFPGAs incorporating cryptographic IP including AES and RSA from Secure-IC. “Security is fast becoming a defining feature of SoCs used in a variety of applications,” said Secure-IC CTO Sylvain Guilley. “The major challenge ...

Maxim has added a physically uncloneable function (PUF) to a 120MHz Arm Cortex-M4 microcontroller for financial and government-grade security, claiming it to be the first. “As IoT applications continue to proliferate, large numbers of devices are being deployed in uncontrolled and hostile areas that make them more vulnerable to physical attacks,” according to the firm. “Maxim’s PUF technology allows for ...

Bristol-based XMOS has developed a processor for artificial intelligence processing in IoT products, combining AI processing, DSP, control and IO. It has been branded xcore.ai and has: 16 real-time logical cores, with support for scalar/float/vector instructions IO ports with nanosecond latency for real-time response Support for binarised (1bit, see below), 8bit, 16 bit and 32bit neural network inference Multi-modal data capture ...

Arm has added the Arm Cortex-M55 processor and the Arm Ethos-U55 NPU for Cortex-M, designed to deliver a combined 480x leap in machine learning (ML) performance to MCUs. Cortex- M55  is Arm’s most AI-capable Cortex-M CPU, and the first to be based on Arm Helium technology, bringing 15x uplift in ML performance and 5x uplift in DSP performance. Ethos-U55 is ...
