Mikrocontroller mit verminderter Betriebsspannung

摘要

The controller operating system provides an external control signal for the micro-controller (MC) in dependence on the operating voltage level, allowing it to switch to a sleep mode during a temporary drop in the operating voltage (Uein). The duration for which the operating voltage remains below a defined min. voltage is timed, for restoring the normal operating mode at the end of the sleep mode, or switching the micro-controller to a reset mode.
