An on-chip i/o-processor for controlling and communication with peripheral devices, wherein an i/o processor core (,), comprising at least one pin controller (,) for reading and setting physical i/o-pins (,), starting timers and generating interrupts for the i/o processor core (,), at least one timer (,) for sampling i/o-pins (,), setting i/o-pins (,) and generating interrupts for the i/o-processor core (,) at well defined points of time, said i/o-processor core (,) providing instructions for controlling said at least one pin controller (,), said at least one timer (,) and i/o-pins (,), an on chip RAM (,) holding instructions for the i/o processor core (,), at least one register (,) for exchanging information between the i/o-processor (,) and a connected CPU (,) on the same chip and inversely, configurable logic (,), connected between said core (,) and said i/o-pins (,), for synchronization of incoming and/or outgoing signals.

On-chip i/o processor supporting different protocols having on-chip controller for reading and setting pins, starting timers, and generating interrupts at well defined points of time
