Product details

170 MHz Cortex-M4 with analog-rich peripheral set

The STM32G473CCU3TR is a 32-bit ARM Cortex-M4 MCU from the STM32G4 series, clocked at 170 MHz with a single-precision FPU and 256 KB of Flash program memory. 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.

Industrial temperature grade and supply range

Operating temperature spans -40 °C to 105 °C. Supply range is 1.71 V to 3.6 V.

Frequently asked questions

What is the maximum clock speed of STM32G473CCU3TR?

The STM32G473CCU3TR runs at 170 MHz from the ARM Cortex-M4 core, with single-precision FPU hardware.

Is STM32G473CCU3TR compatible with STM32G474?

The STM32G473 and STM32G474 share the same STM32G4 architecture and 48-UFQFPN package option, but the G474 typically adds a second ADC core and higher-resolution timer features. Pin compatibility depends on the specific package variant — verify the pinout against the target G474 order code before substituting.

What are the key specifications of STM32G473CCU3TR?

Key specs include a 170 MHz ARM Cortex-M4 core, 256 KB Flash, 128 KB SRAM, 21x12b SAR ADC channels, 7x12b DAC channels, 42 I/O, CANbus, USB, and an operating range of -40 °C to 105 °C at 1.71 V to 3.6 V supply.
