That many ADC channels can handle three-phase current sensing plus a couple of voltage and temperature feedback lines without an external multiplexer. The seven DACs are useful for generating analog setpoints or reference voltages in multi-loop control. ## Active lifecycle — no near-term LTB concern The base product number is STM32G474, and the series is the STM32G4 family, which remains a mainstream offering.","metaTitle":"STMicroelectronics STM32G474RBT6 ARM Cortex-M4F MCU, 170MHz","metaDescription":"STM32G474RBT6 32-bit MCU with 170MHz Cortex-M4F, 128KB Flash, 128KB RAM, 26x12b ADC, 7x12b DAC, CANbus, QSPI. -40°C to 85°C.
