It carries 128 KB of SRAM and a dense analog front-end: 21 channels of 12-bit SAR ADC and 7 channels of 12-bit DAC. The part is aimed at digitally controlled power conversion, motor drives, and industrial sensor fusion where the MCU must close a control loop and handle multiple analog feedback paths simultaneously.","metaTitle":"ST STM32G473CCU3TR ARM Cortex-M4 MCU, 170 MHz, 256 KB Flash","metaDescription":"STM32G473CCU3TR 32-bit MCU with ARM Cortex-M4 at 170 MHz, 256 KB Flash, 128 KB RAM, 21x12b ADC, 7x12b DAC, -40 to 105 °C.
