170 MHz Cortex-M4F with 128 KB flash — what that means for a control-loop design
The STM32G431CBU6 runs a single ARM Cortex-M4F core at 170 MHz. The 18-channel 12-bit ADC and 4-channel 12-bit DAC are the analog front-end that makes this part a fit for applications where the MCU both senses and actuates.
Package and board-fit: 48-UFQFPN exposed pad
The 48-UFQFPN (7x7 mm) package has an exposed pad underneath. The 42 I/O lines fan out to the perimeter; with a 0.50 mm pitch, a 4-layer board is the practical minimum for routing all signals without vias stacking up under the part.
The industrial temperature grade covers most factory-floor and outdoor enclosure environments.
