4.  Run: CPU on, Peripherals on  Idle: CPU off, Peripherals on  Sleep: CPU off, Peripherals off  Run mode 11 μA Typical  Idle mode 2.5 μA Typical  Sleep mode 100 nA Typical  Ultra Low 50nA Input Leakage  Two-Speed Oscillator Start-up 4

5.  Four Crystal modes, up to 40 MHz  4x Phase Lock Loop (PLL) – Available for Crystal and Internal Oscillators  Two External RC modes, up to 4 MHz  Two External Clock modes, up to 40 MHz  Internal Oscillator Block:  Fast wake from Sleep and Idle, 1 μs typical  Secondary Oscillator using Timer1 @ 32 kHz  Fail-Safe Clock Monitor:  Allows for safe shutdown if peripheral clock stops 5

6.  High-Current Sink/Source 25 mA/25 Ma  Three Programmable External Interrupts  Four Input Change Interrupts  Enhanced Capture/Compare/PWM (ECCP) module  One, two or four PWM outputs  Selectable polarity  Programmable dead time  Auto-shutdown and auto-restart 6

7.  Enhanced Addressable USART module:  Supports RS-485, RS-232 and LIN/J2602  10-Bit, up to 13-Channel Analog-to-Digital Converter module:  Auto-acquisition capability  Dual Analog Comparators with Input Multiplexing 7

8.  Alternate Run Modes  Multiple Idle Modes  On-the-Fly Mode Switching  Low Consumption in Key Modules 8

9.  By clocking the controller from the Timer1 source or the internal oscillator block, power consumption during code execution can be reduced by 90%. 9

10.  CPU core disabled but the peripherals still active.  Power consumption can be reduced even further, to as little as 4% of normal operation requirements. 10

11.  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 11

12.  The power requirements for both Timer1 and the Watchdog Timer are minimized 12

13.  Memory Endurance  Self-Programmability  Extended Instruction Set  Enhanced CCP Module  Enhanced Addressable USART  10-Bit A/D Converter  Extended Watchdog Timer (WDT) 13

14.  The Enhanced Flash cells are rated to last for many thousands of erase/write cycles.  Data retention without refresh is conservatively estimated to be greater than 40 years. 14

15.  These devices can write to their own program memory spaces under internal software control.  possible to create an application that can update itself in the field. 15

16.  Introduces an optional extension to the PIC18 instruction set:  which adds 8 new instructions and  an Indexed Addressing mode.  Enabled as a device configuration option:  designed to optimize re-entrant application code originally developed in high-level languages. 16

17.  In PWM mode, this module provides:  1, 2 or 4 modulated outputs for controlling  half-bridge and full-bridge drivers.  Auto-shutdown:  for disabling PWM outputs on interrupt, or other select conditions, and  auto-restart to reactivate outputs once the condition has cleared. 17

18.  Standard RS-232 operation  Provides support for the LIN bus protocol.  Automatic baud rate detection  A 16-bit Baud Rate Generator for improved resolution.  Provides stable operation that talk to the outside world. 18

19.  This module incorporates programmable acquisition time.  Allowing for a channel to be selected  A conversion to be initiated without waiting for a sampling period  Reducing code overhead. 19

20.  Incorporates a 16-bit prescaler  allowing an extended time-out range  stable across operating voltage and temperature. 20
