170 MHz Cortex-M4 with mixed-signal peripherals
The STM32G473CET6: The 20-channel 12-bit ADC and four 12-bit DAC channels let this part sample multiple current-sense or voltage-feedback signals and generate analog setpoints on the same die, reducing the external signal-chain count.
Peripheral set and connectivity
On-chip connectivity includes CANbus, I²C, SPI, UART/USART, USB, QSPI, and SAI — enough to talk to a fieldbus gateway, external NOR flash, and an audio codec without glue logic. The 38 GPIOs in the 48-LQFP package provide enough I/O for a sensor array or a small HMI while keeping the board footprint at 7×7 mm. Built-in brown-out detect, POR, and a watchdog timer cover the basic supervisory functions — no external reset IC needed for most industrial designs.
ROHS3 compliant, meeting the current EU restriction on hazardous substances for new equipment placed on the market.
