The 42-channel 12-bit ADC array and four 12-bit DACs mean this single chip can sample multiple current-sense resistors and phase voltages while generating analog setpoints or reference waveforms — no external ADC mux or extra DAC package needed. 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.
