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.","metaTitle":"STM32G473CET6 STM32G4 MCU, 170 MHz Cortex-M4, 512 KB Flash","metaDescription":"STM32G473CET6, STMicroelectronics STM32G4 series, ARM Cortex-M4 32-bit MCU at 170 MHz, 512 KB flash, 128 KB RAM, 48-LQFP.
