Abstract:
The single chip microcontroller unit includes a processing unit having normal power mode of operation and a low power mode of operation. Analog circuitry and digital circuitry are connected to the processing unit. Monitoring circuitry determines if a chip supply voltage level exceeds a threshold level necessary to maintain operation of the digital circuitry.
