Renesas has introduced a high-end AI MCU family with triple processors and security. The highest spec devices in the ‘RA8P1’ microcontroller family combine a 1GHz Arm Cortex-M85 processor with a 256 MAC/cycle 400MHz Arm Ethos-U55 neural processing unit and a 250MHz Cortex-M33 CPU. “This combination delivers CPU performance of over 7,300 CoreMarks and AI performance of 256Gop/s,” according to the ...

Microchip has created a 78ps-resolution 20bit PWM timer block for a series of MCUs for GaN and SiC based dc-dc converters. There are 16 of them to implement 16 power rails, plus eight 16bit 1.25ns PWMs. The family, dsPIC33AK512MPS512, combines these PWMs with five of the company’s recent 12Bit 40Msample/s ADCs and backs them up with a 200MHz 32bit processing ...

GigaDevice has revealed a family of 48MHz Arm Cortex-M23 microcontrollers. Aimed at industrial use GD32C231, its “Cortex-M23 core architecture offers up to 10% higher performance than Cortex-M0+”, according to the company. 32 to 64kbyte of flash and 12kbyte or ram are available, all with error correction. “An integrated hardware CRC module enhances data transmission integrity,” according to the company, which ...

Infineon has introduced automotive microcontrollers with capacitive touch sensing for sensor and actuator applications. The PSOC 4 HVMS family is built around a 24 or 48MHz Arm Cortex-M0+ processor, with up to 128kbyte of flash and 8kbyte of ram. The ICs also have what Infineon calls ‘high-voltage’ capability for almost-direct connection to 12 and 24V vehicle batteries as they include an ...

Myir has announced a 37 x 39mm system-on-module (SoM) built around NXP’s i.MX 91 processor, which has a single 1.4GHz Arm Cortex-A55 core. “This module maintains pin compatibility with Myir’s existing i.MX93 MYC-LMX9X series, allows customers to scale designs without hardware redesigns,” according to the company. “It is capable of running Linux [6.6.36], making it perfect for electric vehicle charging ...

UK start-up SCI Semiconductor has raised £2.5m towards developing its security-enhanced microcontroller based on CHERI, a memory securing framework developed by the University of Cambridge and supported by the UK and US governments. The investment was from NPIF II – Mercia Equity Finance, which is managed by Mercia as part of the Northern Powerhouse Investment Fund II (NPIF II), and ...

Infineon is shipping introduces PSOC 4100T Plus, an Arm Cortex-M0+ MCU with Multi-Sense. The chip blends analogue and digital capabilities with 128K Flash, 32K SRAM, and Multi-Sense technology which includes CAPSENSE, inductive sensing and liquid level sensing. It claims to provide a complete solution for system control and human-machine interface (HMI) applications. PSOC 4100T Plus can be used as a ...

Towards the end of May, Huawei is reported by the Wall Street Journal to be intending to sample its Ascend 910D AI processor which is aimed at competing with Nvidia’s 2022-vintage Hopper processor H100. Mass production of the 910D is reported to be scheduled for Q1 2026 on SMIC’s 7nm process. It is said that the 910D can be competitive ...

Microchip is aiming at analogue sensors with a microcontroller that can measure signals while consuming less than 3µA while sleeping with one comparator monitoring an in-coming voltage. Called PIC16F17576, it has a power-saving ‘analogue peripheral manager’ (APM). “The APM controls which peripherals are active to minimise total energy consumption and enable battery-operated applications,” according to the company. Inside the APM ...

Microchip has introduced a 32 logic elements programmable logic array into a microcontroller. Each logic element can simulate AND, OR, NAND or NOR gate, a buffer or inverting buffer, a D or JK flip-flop, multiplexers or a four-input look-up table. It is called the CLB (configurable logic block) and it based on an earlier simpler Microchip peripheral called the CLC ...
