170 MHz Cortex-M4F with analog density
Connectivity and peripheral set
On the digital side, the part integrates CAN, I²C, SPI, UART/USART, IrDA, LINbus, and QSPI interfaces — enough to talk to a fieldbus gateway, a serial flash, and several sensor modules without external protocol bridges. The peripheral list includes brown-out detect, DMA, I²S, POR, PWM, and a watchdog timer. With 107 I/O lines available, most of the 128-LQFP pins are usable for general-purpose or alternate-function routing.
Temperature grade and operating envelope
Rated for -40°C to 85°C ambient, the STM32G474QET6U fits industrial environments. Supply voltage spans 1.71 V to 3.6 V. The internal oscillator eliminates the need for an external crystal.
