Description
PIC18LF13K22 offers the advantages of all PIC18 microcontrollers – namely, high computational performance with the addition of high-endurance, Flash program memory. On top of these features, the PIC18(L)F1XK22 family introduces design enhancements that make these microcontrollers a logical choice for many high-performance, power sensitive applications. All of the devices in the PIC18(L)F1XK22 family incorporate a range of features that can significantly reduce power consumption during operation. 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 PIC18(L)F1XK22 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 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) 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 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 32 MHz – all without using an external crystal or clock circuit. Besides its availability as a clock source, the internal oscillator block provides a stable reference source that gives the family additional features for robust operation: Fail-Safe Clock Monitor: This option constantly monitors the main clock source against a reference signal provided by the LFINTOSC. If a clock failure occurs, the controller is switched to the internal oscillator block, allowing for continued operation or a safe application shutdown. Two-Speed Start-up: This option allows the internal oscillator to serve as the clock source from Power-on Reset, or wake-up from Sleep mode, until the primary clock source is available.
