170 MHz Cortex-M4 with analog density — the G473 variant
The headline differentiator versus the G431/G441 siblings is the analog peripheral count: 26 multiplexed 12-bit SAR ADC channels and seven 12-bit DAC outputs, which suits designs needing multiple simultaneous sensor reads or analog actuator outputs without external muxing or extra DAC chips.
Peripheral set and connectivity for system integration
The MCU includes a full set of peripherals: brown-out detect/reset, DMA, I2S, POR, PWM timers, a true random number generator, and a watchdog. Connectivity covers CANbus, I2C, IrDA, LINbus, QSPI, SAI, SPI, UART/USART, and USB — enough for a sensor hub or an industrial fieldbus node. The 52 I/O lines in the 64-LQFP package give headroom for parallel sensor interfaces and display or keypad connections without a port expander.
Lifecycle and sourcing posture
It remains a current-production part suitable for new designs.
