The STM32L433VCT6 connectivity block covers CANbus, I²C, IrDA, LINbus, MMC/SD, QSPI, SAI, SPI, SWPMI, and UART/USART, plus USB.
For a calibration technician or test engineer, this means the part can digitise multiple sensor inputs (thermistors, strain gauges, current shunts) with 12-bit resolution and generate analogue setpoints or reference voltages from the DACs — all on a single chip.
