That FPU handles PID coefficients and sensor fusion math without software emulation, which keeps the interrupt latency tight for motor-drive current loops or CAN message processing. The 2 KB EEPROM stores calibration constants or node IDs without wearing the Flash.
Peripherals and I/O
49 GPIOs bring out the CAN, I²C, SPI, SSI, UART, and IrDA interfaces. The 12-channel 12-bit ADC samples analog inputs for current sensing or potentiometer feedback. Internal oscillator keeps the BOM simple — no external crystal needed for most applications, though a precision clock can be fed in if the CAN bus jitter budget demands it. Brown-out reset, POR, and a watchdog timer handle the power-up sequence and fault recovery without external supervisor ICs.
