ST launches STM32G5 chips with twice the speed for robot hands and datacenters
STMicroelectronics says its new STM32G5 microcontrollers double the compute of the G4 series and can drive up to 20 motors in one humanoid robot hand.
STMicroelectronics has introduced the STM32G5, a new line of mixed-signal microcontrollers aimed at datacenter power supplies, humanoid robots, wind and solar installations, industrial drives and commercial drones. The chips use an Arm Cortex-M33 core running at 280MHz and deliver twice the compute performance of the earlier STM32G4 series. ST says they are in production now.
For robotics, the chip adds a high-resolution timer, a position encoder and a programmable logic array called PLAy. ST points out that a single humanoid hand can need as many as 20 motors. Ruiyan Intelligent CEO Paul Tian said the chip lets his company control more motors and fit more sensors into a robotic hand. Delta Electronics, a customer for power designs, also gave a supportive quote. Security features include an immutable root of trust and post-quantum cryptography libraries.
Why it matters
Small controllers decide how precisely and cheaply a robot hand can move, so faster and better protected chips can help bring dexterous humanoids to market at lower cost. ST has not given prices or named humanoid makers beyond Ruiyan, and the performance claims come from the company itself. Watch for the dual-core STM32G5 products planned for 2027 and for the first robot hands that ship with the chip.
