PIC18F67K22T-I/PTRSL

This document contains device-specific information for the following devices:

This family combines the traditional advantages of all PIC18 microcontrollers – namely, high computational performance and a rich feature set – with an extremely competitive price point. 

These features make the PIC18F87K22 family a logical choice for many high-performance applications where price is a primary consideration.

1.Core Features

XLP TECHNOLOGY

All of the devices in the PIC18F87K22 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.

• 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.

• 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.

• XLP: An extra low-power Sleep, BOR, RTCC and Watchdog Timer

2.OSCILLATOR OPTIONS AND

FEATURES

All of the devices in the PIC18F87K22 family offer different oscillator options, allowing users a range of choices in developing application hardware. These include:

• External Resistor/Capacitor (RC); RA6 available

• External Resistor/Capacitor with Clock Out (RCIO)

• Three External Clock modes:

  - External Clock (EC); RA6 available

  - External Clock with Clock Out (ECIO)

  - External Crystal (XT, HS, LP)

• A Phase Lock Loop (PLL) frequency multiplier, available to the External Oscillator modes, which allows clock speeds of up to 64 MHz. PLL can also be used with the internal oscillator.

• An internal oscillator block that provides a 16 MHz clock (±2% accuracy) and an INTRC source (approximately 31 kHz, stable over temperature and VDD)

   - Operates as HF-INTOSC or MF-INTOSC when block selected for 16 MHz or 500 kHz

   - Frees the two oscillator pins for use as additional general purpose I/O 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, 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.
