The 16-bit RISC CPU16 core gives single-cycle access to the register file, so interrupt latency stays predictable for real-time control loops. The 16 KB Flash is sized for moderate firmware — sensor fusion, motor commutation tables, or a Modbus stack — without needing external memory.
Peripherals and connectivity for sensor and actuator nodes
With 16 I/O lines in the 20-TSSOP package, you get about a dozen usable GPIOs after the serial interfaces are assigned.
