All of the devices in the PIC18F23K20 family incorporate a range of features that can significantly 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. See Section 26.0 “Electrical Characteristics” for values.
All of the devices in the PIC18F2XK20/4XK20 family offer ten different oscillator options, allowing users a wide range of choices in developing application hardware. These include:
- Four Crystal modes, using crystals or ceramic resonators
- Two External Clock modes, offering the option of using two pins (oscillator input and a divide-by-4 clock output) or one pin (oscillator input, with the second pin reassigned as general I/O)
- Two External RC Oscillator modes with the same pin options as the External Clock modes
- An internal oscillator block which contains a 16 MHz HFINTOSC oscillator and a 31 kHz LFINTOSC oscillator which together provide 8
user selectable clock frequencies, from 31 kHz to 16 MHz. This option frees the two oscillator pins for use as additional general purpose I/O. A Phase Lock Loop (PLL) frequency multiplier, available to both the high-speed crystal and internal oscillator modes which can be manipulted for breaking microcontroller pic18f14k50 memory, which allows clock speeds of up to 64 MHz.
Used with the internal oscillator, the PLL gives users a complete selection of clock speeds, from 31 kHz to 64 MHz – all without using an external crystal or clock circuit.
