The STM32G4x3 are mixed-signal microcontrollers with an Arm® Cortex®-M4 core (with FPU and DSP instructions) running at 170 MHz. These are performance devices in the STM32G4 series, which embed a maximum number of analog peripherals.

The devices are equipped with:

  • 5x ultra-fast 12-bit ADCs (4 Msamples/s)
  • 7x 12-bit DACs (15 Msamples/s)
  • 7x ultra-fast comparators (17 nanoseconds)
  • 6x op amps with programmable gain
  • ART, CCM SRAM, and mathematical accelerators
  • Dual-bank Flash memory
  • Up to 3x CAN FD
  • USB 2.0 full-speed data interface (device)
  • USB Type-C™ and power delivery controller (UCPD) 

Memory ranges from 128 to 512 Kbytes and packages with 48 to 128 pins.
