The STM32G474MET6: This part is built for real-time mixed-signal control: it packs 41 channels of 12-bit ADC and 7 channels of 12-bit DAC, alongside a full set of timers and PWM outputs. Typical applications include digital power supplies, motor drives, industrial inverters, and advanced sensing where the MCU handles both the control algorithm and the analog front-end without an external converter. The 170 MHz core with single-cycle multiply-and-accumulate gives the headroom for sensorless field-oriented control loops running at 20 kHz or higher.
80-LQFP package — rework-friendly footprint
Housed in an 80-LQFP (12x12 mm) with 0.4 mm pitch, this package is straightforward to hand-assemble or rework with a standard hot-air station. The exposed pad on the underside needs a thermal via stitch under the QFP for heat sinking if the part runs continuous PWM at high ambient — the datasheet's thermal resistance figures assume that pad is soldered to a copper plane.
The internal oscillator means you can bring up the core without an external crystal, though the HSE input is available if you need tighter timing for USB or CAN.
Connectivity and peripheral set
On the communication side, the STM32G474MET6 includes CANbus, I²C, SPI, QSPI, UART/USART, and IrDA — enough to interface with industrial fieldbuses, external ADCs, or serial flash for data logging. The 66 GPIOs give room for parallel displays or multiple encoder inputs without a port expander. Brown-out detect and POR are integrated, so external supervisor ICs are optional for most applications.
