Faster wide-bandgap power stages need sharper control, and STMicroelectronics is building STM32G5 microcontrollers to match them
STMicroelectronics has started production of its STM32G5 microcontrollers, which double the compute of the STM32G4 series for real-time control of power converters and electric motors. ST leads on datacentres and robotics, though Delta Electronics already sees a role for the chips in electric vehicle (EV) applications.
The automotive link lies in power electronics. A 280MHz Arm Cortex-M33 core is paired with ST’s upgraded 12-channel high-resolution timer, debuting on this series and precise enough to manage the faster switching of silicon carbide and gallium nitride power stages now common in EVs.
Motor-control timers, a position encoder and post-quantum cryptography support complete the package. Prices start at US$1.03 in 10,000-unit orders, with dual-core versions due in 2027.
“Digital power is at the heart of our mission to deliver innovative, clean, and energy-efficient solutions for a better tomorrow, and it requires control platforms that can keep pace with increasingly complex systems,” Andy Hsiao, Senior Commodity Buyer, PSBG Materials Division at Delta Electronics, said. “The STM32G5 brings the level of performance and flexibility needed for next-generation digital-power applications. The combination of processing power, integrated peripherals, and built-in security makes it a strong option for our designs, helping deliver lower energy losses, a smaller footprint, and higher reliability in demanding AI and EV applications.”
