STMicro Starts Production of STM32G5 Microcontrollers
The new STM32G5 family doubles the compute of its predecessor, targeting real-time control of power converters and electric motors.
Updated on Nov. 4, 2026 in Semiconductors
STMicroelectronics has started production of its STM32G5 microcontrollers, which double the compute of the STM32G4 series. The chips are aimed at real-time control of power converters and electric motors.
Why it matters
Faster wide-bandgap power stages built on silicon carbide and gallium nitride require sharper control, and the STM32G5 is positioned to meet that demand. The chips therefore address a growing need in power electronics.
The microcontrollers pair a 280MHz Arm Cortex-M33 core with a 12-channel high-resolution timer that debuts on this series, starting at US$1.03 per unit in 10,000-unit orders. The source does not give volume ramp figures or pricing for smaller orders.
The players
STMicroelectronics
STMicroelectronics is a European semiconductor manufacturer that produces microcontrollers and power electronics components for industrial and automotive markets.
Delta Electronics
Delta Electronics is a Taiwan-based power electronics company that evaluates components for electric vehicle and industrial power applications.
The details
The STM32G5 includes motor-control timers, a position encoder, and post-quantum cryptography support. Delta Electronics sees a role for the chips in electric vehicle applications, where the high-resolution timer is precise enough to manage faster switching in power stages.
Timeline
November 4, 2026: STMicroelectronics announces production start of the STM32G5 microcontrollers.
2027: Dual-core STM32G5 versions are due.
The Tech Race
The STM32G5 extends the control layer needed by silicon carbide and gallium nitride power stages, which switch faster than legacy silicon devices. Its high-resolution timer targets that switching speed directly.
Engineers designing motor drives and power converters gain a microcontroller with more compute and a finer timer for fast-switching power stages. The starting price of US$1.03 applies only to 10,000-unit orders, so smaller buyers should expect different pricing.
The takeaway
Hardware makers building power electronics should watch how microcontroller timing keeps pace with faster wide-bandgap switching. The STM32G5 shows that control silicon is being updated alongside the power devices it manages.
