STMicro's new 280 MHz MCU doubles performance for power supplies, EV chargers, and robotics

STMicroelectronics has launched the STM32G5 series, a family of 280 MHz Arm Cortex-M33 mixed-signal microcontrollers aimed at industrial applications. These chips are specifically designed for digital power supplies, photovoltaic inverters, electric vehicle charging stations, robotics, and motor control systems, delivering double the performance of the company's 2021-era STM32G4 series.

The new MCUs pack up to 512KB of flash memory, 112KB of SRAM with error correction, and a high-resolution timer precise to 111 picoseconds for generating complex PWM signals. For engineers designing the next generation of industrial and automotive systems, this combination of raw speed, mathematical accelerators for trigonometry and filtering, and built-in security features like Arm TrustZone and post-quantum cryptography support provides a significant performance and feature leap. The takeaway: STMicro is aggressively pushing the envelope for embedded control in demanding real-time applications.
