Microcontroller

All of the devices in the PIC18F2420/2520/4420/4520family incorporate a range of features that can signifi-cantly reduce power consumption during operation.Key items include:•Alternate Run Modes: By clocking the controller from the Timer1 source or the internal oscillator block, power consumption during code execution can be reduced by as much as 90%.•Multiple Idle Modes: The controller can also run with its CPU core disabled but the peripherals still active. In these states, power consumption can be reduced even further, to as little as 4% of normal operation requirements.•On-the-Fly Mode Switching: The power-managed modes are invoked by user code during operation, allowing the user to incorporate power-saving ideas into their application’s software design.•Low Consumption in Key Modules: The power requirements for both Timer1 and the Watchdog Timer are minimized.
