Product details

170 MHz Cortex-M4 with rich analog front-end

The STM32G473QET6 is a 32-bit ARM Cortex-M4 MCU from STMicroelectronics' STM32G4 series, clocked at 170 MHz with a single core.

Lifecycle — EOL hot, last-time-buy window active

This part carries an EOL hot lifecycle status. The base product number STM32G473 points to the same footprint.

The 170 MHz core speed enables real-time control loops. The 128 KB RAM supports data buffers for logging or waveform capture.

Pinout and package — 128-LQFP, 14x14 mm

The 107 I/O include multiple alternate-function mappings.

Frequently asked questions

Does STM32G473QET6 support CANbus?

Yes, the connectivity set includes CANbus alongside I²C, SPI, UART/USART, USB, and QSPI.

What is the closest pin-compatible alternative to STM32G473QET6?

Within the STM32G473 family, other density variants (e.g., STM32G473CET6 with 512 KB Flash in a smaller package, or STM32G473RET6 with 512 KB Flash in 64-pin LQFP) share the same core and peripheral set but differ in pin count and package. For a direct 128-LQFP drop-in, check the STM32G474QET6 which offers additional HRTIM features — verify pin compatibility in the datasheet.

What is STM32G473QET6's listed speed?

The core runs at 170 MHz, which is the maximum clock for this STM32G4 device.

What is the operating temperature range?

Rated for -40°C to 85°C (TA), which covers industrial and most commercial environments.
