STMicroelectronics launches STM32G5 microcontrollers targeting AI data centers and robotics
Unveiled in a press release on November 4, 2026, the group's new generation of microcontrollers delivers computing performance twice that of the STM32G4 series. It is initially intended for power supplies in AI data centers and motor control in robotics.
From AI Data Centers to Humanoid Robots
The group presents the STM32G5 series as a contribution to what it calls "the physical AI revolution". Target markets include data centers, robotics, photovoltaic and wind installations, industrial drives and commercial drones.
Patrick Aidoune, General Manager of the Standard and Automotive Microcontrollers division, explained that this generation "meets the challenge of efficiently satisfying the growing energy needs of AI data centers, building more sophisticated humanoid robots and powering more complex motor control systems".
The press release indicates that rack power is trending toward 1 MW with the latest GPU clusters, and that the largest data centers could require more than 2 GW of peak power by 2030. In humanoid robotics, a single hand can have up to 20 motors.
Post-Quantum Security, First Customers and Expansion in 2027
The microcontrollers are based on an Arm Cortex-M33 core clocked at 280 MHz and notably integrate an enhanced high-resolution timer, a position encoder and a programmable logic matrix called PLAy. According to ST, this timer makes it possible to dynamically reconfigure power supplies according to server load.
It should also manage the higher switching frequencies of power supplies designed with silicon carbide and gallium nitride semiconductors. On the security side, the series combines Arm TrustZone technology with the group's proprietary STM32Trust features and supports its post-quantum cryptography libraries.
Two customers are cited. For Andy Hsiao of Delta Electronics, the series helps "reduce energy losses and footprint and enhance reliability in demanding AI and electric vehicle applications".
Paul Tian, General Manager of Ruiyan Intelligent, highlights the ability to control more motors and integrate more sensors in the robotic hand.
The STM32G5 microcontrollers are now in production, with embedded Flash memory from 64 KB to 512 KB and packages ranging from QFN32 to LQFP128. Prices start at $1.0340 for orders of 10,000 units, and the single-core portfolio will be expanded in 2027 with dual-core products.
