Description
PIC18LF45J10 offers the advantages of all PIC18 microcontrollers – namely, high computational performance at an economical price. The PIC18F45J10 family introduces design enhancements that make these microcontrollers a logical choice for many high-performance, power sensitive applications All of the devices in the PIC18F45J10 family incorporate a range of features that can significantly reduce power consumption during operation 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 powermanaged 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 PIC18F45J10 family offer three different oscillator options. These include: Two Crystal modes, using crystals or ceramic resonators Two External Clock modes INTRC source (approximately 31 kHz) 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 internal oscillator. If a clock failure occurs, the controller is switched to the internal oscillator block, allowing for continued low-speed 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
