This family offers the advantages of all PIC18 microcontrollers namely, high – computational performance at an economical price with the addition of high-endurance, Flash – program memory. On top of these features, the PIC18(L)F2X/4XK22 family introduces design enhancements that make these microcontrollers a logical choice for many highperformance, power sensitive applications. All of the devices in the PIC18(L)F2X/4XK22 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. All of the devices in the family offer ten different oscillator PIC18(L)F2X/4XK22 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 • 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 •
