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. The surface-mount LQFP is hand-solderable with a fine tip and a decent flux, though the 0.5 mm pitch means a clean stencil and a preheat zone if you're reworking a board that's already been through the oven. MSL 3 out of the bag — bake before reflow if the moisture barrier envelope has been open past the floor-life window. ## Industrial temperature range and active lifecycle The product status is Active per ST's current lifecycle record — no NRND flag, no last-time-buy notice. For a production BOM that needs a guaranteed supply horizon through at least the next few years, this part sits in the safe lane. 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.
