It packs 512 KB of Flash and 128 KB of SRAM, with a rich set of analog peripherals: 21 channels of 12-bit SAR ADC and 7 channels of 12-bit DAC. ## 512 KB Flash and 128 KB RAM — firmware budget The 512 KB program memory and 128 KB SRAM give this MCU enough headroom for field-oriented control (FOC) libraries, real-time communication stacks (CANopen, USB), and moderate data logging. The 170 MHz core keeps the loop rate tight for switching power supplies and servo drives.","metaTitle":"ST STM32G473CEU3TR ARM Cortex-M4 MCU, 170 MHz, 512 KB Flash","metaDescription":"STMicroelectronics STM32G473CEU3TR 32-bit MCU, 170 MHz Cortex-M4, 512 KB Flash, 128 KB RAM, 21x12b ADC, 7x12b DAC, -40 to 105 °C, 48-UFQFPN.
