The CANbus, QSPI, and SAI interfaces tie it into industrial fieldbus, external Flash, or audio codecs without glue logic. ## 86 I/Os in a 100-LQFP — routing and footprint reality The 100-LQFP package (14x14 mm body) brings out 86 general-purpose I/Os. That's enough to capture a resolver interface, a few encoder channels, a parallel LCD bus, and still have pins left for UART debug and pushbuttons. ## Industrial temperature range and active lifecycle The base product number is STM32G473, which means the same peripheral set scales across the VBT6 (128 KB) and higher-density siblings in the same 100-pin footprint. ## Peripheral set for mixed-signal control designs Beyond the ADC and DAC count, the STM32G473VBT6 integrates a full set of timers with PWM generation, a brown-out detect/reset circuit, DMA controllers, and a watchdog timer. Connectivity covers CANbus, I²C, SPI, UART/USART, USB, IrDA, LINbus, QSPI, and SAI — enough to talk to almost any peripheral on the board without a protocol bridge.","metaTitle":"STM32G473VBT6 STM32G4 ARM Cortex-M4 MCU, 170 MHz","metaDescription":"STM32G473VBT6 32-bit MCU with 170 MHz Cortex-M4, 128 KB Flash, 128 KB RAM, 42x12b ADC, 4x12b DAC, CANbus, QSPI.
