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. It carries 512 KB of Flash and 128 KB of RAM, backed by a full set of peripherals including CANbus, I²C, SPI, UART/USART, USB, and QSPI. The analog side is unusually dense: 42 channels of 12-bit ADC and 7 channels of 12-bit DAC, making this part a natural fit for multi-phase motor control, digital power conversion, or instrumentation where you need to sample several feedback paths simultaneously. The 107 I/O lines in a 128-LQFP package give plenty of headroom for parallel sensor interfaces or external memory buses.
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.
170 MHz — what it means for the control loop
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 STM32G473QET6 is supplied in a 128-LQFP package with a 14x14 mm body. The 107 I/O include multiple alternate-function mappings.
