This family of devices 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. In addition to these features, the PIC18F2450/4450 family introduces design enhancements that make these microcontrollers a logical choice for many high-performance, power sensitive applications when Read MCU.

All of the devices in the PIC18F2450/4450 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 RC oscillator, power consumption during code execution can be reduced by as much as 90% if Read 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.

· 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 before Read MCU.

· Low Consumption in Key Modules: The power requirements for both Timer1 and the Watchdog Timer are minimized. See Section 21.0 “Electrical Characteristics” for values.

Devices in the PIC18F2450/4450 family incorporate a fully featured Universal Serial Bus communications module that is compliant with the USB Specification Revision 2.0. The module supports both low-speed and full-speed communication for all supported data transfer types. It also incorporates its own on-chip transceiver and 3.3V regulator and supports the use of external transceivers and voltage regulators after Read MCU.

All of the devices in the PIC18F2450/4450 family offer twelve different oscillator options, allowing users a widerange of choices in developing application hardware. These include:

· Four Crystal modes using crystals or ceramic resonators if Read MCU.

· Four 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).

· An INTRC source (approximately 31 kHz, stable over temperature and VDD). This option frees an oscillator pin for use as an additional general purpose I/O. A Phase Lock Loop (PLL) frequency multiplier, available to both the High-Speed Crystal and External Oscillator modes, which allows a wide range of clock speeds from 4 MHz to 48 MHz.

· Asynchronous dual clock operation, allowing the USB module to run from a high-frequency oscillator while the rest of the microcontroller is clocked from an internal low-power oscillator when Read MCU.

The internal oscillator 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, allowing for continued low-speed operation or a safe application shutdown before Read 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 after Read MCU.
