STMicro STSPIN32G0 3-phase motor controllers support up to 24V for portable appliances, up to 600V for industrial automation

STMicro STSPIN32G0 is a new series of advanced 3-phase motor controllers with variable voltage ranging from 45V to 600V that extend STMicro’s portfolio of devices with an integrated MCU and motor driver. The new series combines a triple-half bridge gate driver with the Arm Cortex-M0+-based STM32G0 microcontroller and is capable of handling six-step and field-oriented control (FOC) algorithms. The integrated design of the STSPIN32G0 series offers cost-savings and “significant BOM area reduction without compromising performance and robustness.” There are two main versions of the STSPIN32G0 series, low-voltage and high-voltage. The low-voltage 3-phase motor controllers include a voltage regulator, one or three shunts, and a gate driver rated at 45V and up to 0.6A. They are mainly targeted at home appliances, power tools, and drones. The high-voltage versions can handle either 250V or 600V, making them suitable for industrial inverters and fans. They are targeted at home appliances, air conditioners, home […]

Renesas RA8E1 and RA8E2 entry-level Arm Cortex-M85 MCUs target cost-sensitive applications

Fast Prototyping Board for Renesas RA8E1

Renesas has expanded its Arm Cortex-M85-based RA8 series to include two new entry-level MCUs, RA8E1 and RA8E2. The new microcontrollers perform similarly to other Arm Cortex-M85-based microcontrollers and are offered at a lower price point thanks to a streamlined feature set to reduce costs. The RA8E1 and RA8E2 groups of microcontrollers will be useful for high-volume applications in industrial and home automation, healthcare, office equipment, and consumer products. We have previously covered other models in Renesas’ RA8 series, including the Renesas RA8T1, RA8D1, and the very first Cortex-M85 microcontroller, the Renesas RA8M1. The RA8 series consists of microcontrollers based on the Arm Cortex-M85 core with a performance of 6.39 CoreMark/MHz and Arm’s M-Profile Vector Extension which provides a 4x performance boost for DSP and ML workloads while maintaining low power consumption. The RA8E1 and RA8E2 Cortex-M85 microcontroller groups differ mostly in clock speed, available internal and external memory, communication interfaces, […]
