STM32G4 Mixed-Signal Microcontrollers (MCUs)

STMicroelectronics STM32G4 Mixed-Signal Microcontrollers (MCUs) combine a 32-bit Arm® Cortex®-M4 core (with FPU and DSP instructions) running at 170MHz. This is combined with three hardware accelerators: ART Accelerator™, CCM-SRAM routine booster, and mathematical accelerators. A flexible interconnect matrix allows autonomous communication between peripherals and saves CPU resources and power consumption. A high degree of compatibility with the STMicroelectronics STM32F3 Series guarantees outstanding efficiency when designing derivatives of applications at different performance levels.
