Product details

STM32G473QCT6 ARM Cortex-M4 MCU at 170 MHz with 256 KB Flash, 128K x 8 SRAM, 42x12-bit ADC, 7x12-bit DAC, and on-die CANbus, USB, QSPI, UART/SPI/I²C interfaces.

Analog front end: 42 ADC channels and 7 DAC outputs

With 42 analog inputs and seven DAC outputs, this MCU can simultaneously monitor three-phase motor currents, a DC-link voltage, and a temperature sensor while generating PWM reference voltages or analog setpoints. The 12-bit resolution on both converters is adequate for most industrial control loops; if you need higher precision, an external ADC is the next step. The data converter count alone tells you this is a mixed-signal part, not a general-purpose controller.

Lifecycle and sourcing posture

It is a current-production part from STMicroelectronics, available through independent distribution.

Frequently asked questions

Is STM32G473QCT6 compatible with STM32G474QCT6?

Yes, the STM32G473QCT6 and STM32G474QCT6 are pin-compatible in the same 128-LQFP package. The G474 adds a high-resolution timer (HRTIM) peripheral for advanced power conversion; the G473 omits it. If your firmware does not use HRTIM, the two parts are drop-in replacements for dual-sourcing.

Does STM32G473QCT6 have a built-in USB interface?

Yes, the connectivity set includes USB (listed under USB in the Connectivity field), along with CANbus, I²C, SPI, UART/USART, QSPI, and SAI.
