The STM32G4 series combines a 32-bit Arm® Cortex®-M4 core (with FPU and DSP instructions) running at 170 MHz combined with three different hardware accelerators: ART Accelerator, CCM-SRAM routine booster, and mathematical accelerators.
The STM32G4 series also offers:
- Rich advanced analog peripherals (comparator, op amp, DAC)
- ADC with hardware oversampling (16-bit resolution)
- Dual-bank flash memory with error-correcting code (ECC), supporting in-field firmware upgrades
- Securable memory area
- High-resolution timer version 2
- USB Type-C® interface with power delivery including physical layer (PHY)
- AES hardware encryption
A flexible interconnect matrix allows autonomous communication between peripherals and saves CPU resources and power consumption.
A high degree of compatibility with the STM32F3 series guarantees outstanding efficiency when designing derivatives of applications at different performance levels.
