Product details

170 MHz Cortex-M4 with analog-rich peripheral set

The analog front end integrates 26 channels of 12-bit ADC and four 12-bit DAC channels, reducing external signal-chain components for applications like servo drives, solar inverters, or battery-management systems where multiple analog feedback paths are needed. Connectivity includes CANbus, USB, QSPI, SAI, I2C, SPI, and multiple UART/USART interfaces, covering fieldbus, external memory expansion, and audio codec links without glue logic.

The 64-LQFP (10x10 mm) package with 52 accessible I/O fits 2-layer PCB layouts and hand-assembly or reflow processes.

Frequently asked questions

Can STM32G473RET6 be used in place of STM32G474RET6?

The STM32G474RET6 is a close sibling in the same STM32G4 family, typically offering additional HRTIM (high-resolution timer) features for advanced power conversion. The STM32G473RET6 lacks that specific timer peripheral. Pin compatibility and memory sizing should be verified against the respective datasheets before substitution.

What development board supports STM32G473RET6?

STMicroelectronics offers the NUCLEO-G473RE development board, which is built around the STM32G473RE (the same core with 512 KB Flash in an LQFP-64 package). It provides Arduino and ST morpho connectivity for prototyping.
