Typical uses include digital power supplies, motor control loops, and industrial sensing where the combination of a floating-point unit and on-chip analog saves board space and BOM cost. The 170 MHz core speed with a single-cycle multiply-and-accumulate and hardware divide gives this MCU the headroom to run a field-oriented motor control loop or a multi-phase digital power supply algorithm in software rather than requiring a separate DSP or FPGA. The floating-point unit handles trigonometric and filter calculations without fixed-point scaling overhead, which simplifies firmware development for sensor fusion or adaptive control. ## On-chip ADC and DAC — analog integration that reduces external parts With 11 analog inputs multiplexed into a 12-bit ADC and four independent 12-bit DAC outputs, the STM32G431K8T6 can digitise multiple current-sense or voltage-feedback signals and generate analog setpoints or reference voltages on the same die. This integration eliminates the need for external ADC or DAC ICs in many designs, shrinking the PCB and simplifying the supply chain. The DAC channels are useful for trimming offsets or generating analog modulation signals in power-converter applications. ## Connectivity and peripheral set for industrial communication The 26 I/O lines in the 32-LQFP package provide enough pins for a modest sensor array or a few external peripherals while keeping the footprint compact at 7x7 mm.","metaTitle":"STM32G431K8T6 MCU, ARM Cortex-M4F 170MHz, 64KB Flash","metaDescription":"STM32G431K8T6 32-bit MCU with ARM Cortex-M4F at 170MHz, 64KB Flash, 32KB SRAM, 11x12b ADC, 4x12b DAC.
