The Cortex-M4 core includes a single-cycle multiply and hardware divide, plus a DSP extension for signal-processing tasks like motor-control FOC loops or audio filtering.
On-chip peripherals include DMA, I²S, LVD, POR, PWM, and WDT. The DMA engine offloads the CPU for data transfers between peripherals and memory, useful for buffered serial streams. I²S provides a digital audio interface for codec or MEMS microphone input. The PWM module supports motor-drive or LED-dimming waveforms with dead-time insertion. The 10-channel 16-bit ADC gives 16-bit resolution for analog sensor acquisition, with a conversion rate that keeps up with real-time control loops.
Housed in a 32-VFQFN with exposed pad (5x5 mm body), this package is compact for space-constrained PCBs. The wettable flank option improves solder-joint inspection and rework reliability — the side pads wick solder up for a visible fillet.
