Renesas RA0 Cortex-M23 MCU series target power and cost-sensitive applications

Fast Prototyping Board for RA0E1

Renesas has announced the new low-power RA0 microcontroller series based on the power-efficient Arm Cortex-M23 core and the entry-level RA0E1 Group in the series. According to Renesas, the RA0 microcontrollers offer the “industry’s lowest overall power consumption for general-purpose 32-bit MCUs.” With a current consumption of 84.3 μA/MHz in active mode and only 0.82 mA in sleep mode, these microcontrollers are built to provide ultra-low power consumption. They also offer a Software Standby mode where the CPU, peripheral functions, and internal oscillators cease to operate. This mode reduces power consumption further by 99% down to 0.20 µA. They also come with a high-precision, High-speed On-Chip Oscillator (HOCO) for fast wake-up. The Cortex-M23 core is based on the Armv8-M instruction set and offers a maximum clock frequency of 32 MHz, with up to 64KB of code flash memory and 12KB SRAM  for storing application code and data. This feature set makes […]

Arm Ethos-U85 NPU delivers up to 4 TOPS for Edge AI applications in Cortex-M7 to Cortex-A520 SoCs

Arm Ethos-U85 NPU

Arm has just Introduced its third-generation NPU for edge AI with the Arm Ethos-U85 that scales from 256 GOPS to 4 TOPS or up to four times the maximum performance of the previous generation Ethos-U65 microNPU, while also delivering 20% higher power efficiency. While previous Arm microNPUs were paired with Cortex-M microcontroller-class cores potentially embedded into a Cortex-A application processor, the new Ethos-U85 can be married with Cortex-M microcontrollers and Cortex-A application processors up to the Cortex-A510/A520 Armv9 cores. Arm expects the Ethos-U85 to find its way into SoC designed for factory automation and commercial or smart home cameras with support for the new Transformer Networks and the more traditional Convolutional Neural Networks (CNNs). The Arm Ethos-U85 supports 128 to 2,048 MACs with performance ranging from 256 GOPS to 4 TOPS at 1 GHz, embeds 29 to 267KB RAM, offers SRAM, DRAM, and flash interface for external memory, and up […]
