STM32G4 series
Mainstream MCUs
STM32G4 mixed-signal MCUs shaped for analog-rich applications
The STM32G4 series combines
powerful Arm® Cortex®-M4 plus
FPU and DSP capability with rich
and advanced analog peripherals.
It introduces two new mathematical
accelerators (Cordic and Filtering),
CAN-FD (Flexible Datarate),USB
Type-C interface with Power
Delivery including physical layer
(PHY) and advanced security with
safety features.
Its new high-resolution timer
V2.0 continues the Digital Power
success story.
Designed for Motor Control applications
