Présentation

Description

The STM32G474RBT6 is a high-performance ARM Cortex-M4 microcontroller from STMicroelectronics, featuring a 170 MHz core with FPU and DSP support. It includes 128 KB Flash, 32 KB SRAM, and 16 KB EEPROM, making it ideal for real-time control and digital signal processing.
Key features:
- Rich peripherals: Multiple ADCs, DACs, timers, and USART/SPI/I2C interfaces.
- Advanced analog: 12-bit ADCs (5 Msps), 12-bit DACs, and comparators.
- High-resolution PWM (HRTIM): Up to 184 ps resolution for precise motor control.
- Low-power modes: Supports energy-efficient applications.
- Hardware crypto: AES-128/256, PKA, and RNG for security.
Packaged in a 64-pin LQFP, it suits industrial, automotive, and consumer applications requiring high-speed processing and analog precision.
