The 100-LQFP package (14x14 mm) gives 86 usable I/O, enough to handle multiple encoder inputs, PWM phases, and sensor interfaces without a port expander. ## 42 ADC channels and 7 DACs — analog density for multi-loop systems A 42-channel 12-bit ADC and a 7-channel 12-bit DAC sit on-chip, giving this part an unusually dense analog front-end for a mid-range MCU. In a three-phase motor drive, that means one chip can sample all phase currents, DC-link voltage, and temperature while the DACs output reference levels or analog telemetry — no external mux or extra DAC IC. The 12-bit resolution is adequate for current-sense feedback in most industrial servo loops; if you need 16-bit, you step up to the G474's higher-density siblings or add an external ADC.","metaTitle":"ST STM32G474VBT3 MCU, ARM Cortex-M4F 170MHz, 128KB Flash","metaDescription":"STMicroelectronics STM32G474VBT3 32-bit MCU with ARM Cortex-M4F at 170MHz, 128KB Flash, 128K x 8 RAM, 42x12b ADC, 7x12b DAC, -40 to 125°C.
