Semiconductor chip with an integrated microprocessor and a real time clock

摘要

It is a semiconductor chip with an integrated microprocessor (mc) and an integrated real time clock (ezu) is described, wherein the microprocessor (mc) and the real time clock (ezu) mutually independent power supplies have, wherein the real time clock (ezu) a real time period of time transmitter (rtc), whose output is connected to a number of comparators (v1, vm) is connected, each of which, with an associated writable compare register (vr1, vrm) are connected, wherein the outputs of the comparator (v1, vm) in each case with a configurable alarm unit (ae1, aem) are connected, which are arranged, at their outputs to provide a plurality of different alarm reactions, and wherein the real time clock (ezu) a number of the start / stop - counters (ssz1, sszk), whose start - and stop inputs in each case with at least one of the outputs of the alarm units (ae1, aem) are connected.
