New Microcontroller Doubles Power Control Compute
The STM32G5 pairs a 280MHz core with a precision timer for silicon carbide and gallium nitride power stages, with dual-core versions due in 2027.
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 in production now; dual-core versions are due in 2027, so those are announced rather than shipped.
Why it matters
Faster wide-bandgap power stages built on silicon carbide and gallium nitride switch more quickly, and they demand sharper control to match. The STM32G5 targets that gap by pairing precise timing with real-time control of power converters and electric motors.
The manufacturer states the STM32G5 doubles the compute of the STM32G4 and pairs a 280MHz Arm Cortex-M33 core with a 12-channel high-resolution timer, which debuts on this series. Starting price is US$1.03 at 10,000 units, but no independent benchmark figures were reported.
The players
STMicroelectronics
A European semiconductor maker whose STM32 microcontroller line is a major product family in industrial and automotive control.
Delta Electronics
A power-electronics manufacturer evaluating the STM32G5 for electric vehicle applications.
The details
The chips act as microcontrollers, small processors that run control loops inside equipment. The high-resolution timer is precise enough to manage the faster switching of silicon carbide and gallium nitride power stages, which switch faster than older silicon parts. The series also includes motor-control timers, a position encoder, and post-quantum cryptography support.
Timeline
Production of the STM32G5 began as of November 4, 2026.
Dual-core STM32G5 versions are due in 2027.
The Tech Race
The STM32G5 extends STMicroelectronics' STM32G4 line, which it doubles in compute while adding a timer aimed at faster wide-bandgap power stages. The move positions the family for power-electronics designs that the STM32G4 was not built to match.
Engineers building power converters and motor drives can evaluate the STM32G5 now, with starting pricing of US$1.03 at 10,000-unit orders. Availability at smaller volumes and the timeline for the dual-core versions were not reported.
The takeaway
Watch for the dual-core STM32G5 versions due in 2027 and for independent benchmarks of the high-resolution timer against silicon carbide and gallium nitride designs. Those results will show whether the doubled compute holds up in production power electronics.
What happens next
Dual-core STM32G5 versions are due in 2027, a date the manufacturer has projected rather than confirmed.
