The microcontrollers also integrate essential peripheral functions for system control, including a 12‑bit analog‑to‑digital converter (ADC), timers, universal asynchronous receiver/transmitter (UART), serial peripheral interface (SPI), inter‑integrated circuit (I²C^[2]), and direct memory access (DMA^[3]). An additional feature is an advanced programmable motor driver (A‑PMD) that supports brushless DC motor control, ensuring flexible use in line with application requirements and system configurations.
