Product details

It packs 512 KB of Flash and 128 KB of SRAM, enough for mixed-signal control firmware with room for OTA staging.

Analog and connectivity peripherals for a mixed-signal design

This MCU integrates 20 analog-to-digital converters at 12-bit resolution and 7 digital-to-analog converters at 12-bit, so a single chip can handle current sensing, voltage feedback, and analog output generation without external converters. The peripheral set includes CANbus, I²C, SPI, UART/USART, USB, QSPI, and SAI, plus PWM timers and a watchdog.

Frequently asked questions

How to program STM32G473CET3?
