Extract MCU PIC18F2523 Program

We can Extract MCU PIC18F2523 Program, please view the MCU PIC18F2523 features for your reference:

This family offers the advantages of all PIC18 microcontrollers – namely, high computational performance at an economical price – with the addition of high-endurance, Enhanced Flash program memory when Extract MCU.

On top of these features, the PIC18LF2423/2523/4423/4523 family introduces design enhancements that make these microcontrollers a logical choice for many high-performance, power sensitive applications if Extract MCU.

All of the devices in the PIC18F2423/2523/4423/4523 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% after Extract MCU.

· 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 before Extract MCU.

· 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 PIC18LF2423/2523/4423/4523 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 before Extract MCU.

· 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 after Extract MCU.

· An internal oscillator block which provides an 8 MHz clock and an INTRC source (approximately 31 kHz), as well as a range of six user-selectable clock frequencies, between 125 kHz to 4 MHz, for a total of 8 clock frequencies. This option frees the two oscillator pins for use as additional general purpose I/O if Extract MCU.

· 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 40 MHz from the HS clock source. 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 internal oscillator. If a clock failure occurs, the controller is switched to the internal oscillator block, allowing for continued operation or a safe application shutdown when Extract MCU.

· 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.
