PIC18 Microcontroller Family

The PIC18 microcontroller family provides PICmicro®

devices in 18- to 80-pin packages, that are both socket

and software upwardly compatible to the PIC16 family. The

PIC18 family includes all the popular peripherals, such as

MSSP, ESCI, CCP, flexible 8- and 16-bit timers, PSP, 10-bit

ADC, WDT, POR and CAN 2.0B Active for the maximum

flexible solution. Most PIC18 devices will provide FLASH

program memory in sizes from 8 to 128 Kbytes and data

RAM from 256 to 4 Kbytes; operating from 2.0 to 5.5 volts,

at speeds from DC to 40 MHz. Optimized for high-level

languages like ANSI C, the PIC18 family offers a highly

flexible solution for complex embedded applications.

High Performance RISC CPU:

• 77 instructions

• C-Language friendly architecture

• PIC16 source code compatible

• Linear program memory addressing to 2 Mbyte

Analog Features (Continued):

• Linear data memory addressing up to 4 Kbytes

• Up to 10 MIPs operation:

• Programmable Low Voltage Detection (LVD) module

– Supports interrupt-on-low voltage detection

• Programmable Brown-out Reset (BOR)

• Comparators

– DC - 40 MHz osc/clock input

– 4 MHz - 10 MHz clock with PLL active

• 16-bit wide instructions, 8-bit wide data path

• Priority levels for interrupts

• 8 x 8 Single Cycle Hardware Multiplier

Special Microcontroller Features:

• Power-on Reset (POR), Power-up Timer (PWRT) and

Oscillator Start-up Timer (OST)

Peripheral Features:

• High current sink/source 25 mA/25 mA

• Up to four external interrupt pins

• Up to three 16-bit timer/counters

• Up to two 8-bit timer/counters with 8-bit period

– Capture input: 16-bit, resolution 6.25 ns (TCY/16)

– Compare: 16-bit, max. resolution 100 ns (TCY)

– PWM output: PWM resolution is 1- to 10-bit

Max. PWM frequency @: 8-bit resolution = 156 kHz

10-bit resolution = 39 kHz

• Wide operating voltage range (2.0V to 5.5V)

• Industrial and Extended temperature ranges

Power Managed Features:

• Dynamically switch to secondary LP oscillator

• Internal RC oscillator for ADC operation during SLEEP

• SLEEP mode (IPD < 1 µA typ.)

• Master Synchronous Serial Port (MSSP) module

Two modes of operation:

– 3-wire SPI (supports all 4 SPI modes)

– up to 23 individually selectable wake-up events

– 3 edge selectable wake-up inputs

– 4 state change wake-up inputs

– I C Master and Slave mode

• Up to 2 Addressable USART modules (ESCI)

– Supports interrupt on Address bit

• Parallel Slave Port (PSP) module

• Internal RC oscillator for WDT (period wake-up)

• RAM retention mode (VDD as low as 1.5V)

• Up to 6 more Power Managed modes available on

selected models (PIC18F1320/2320/4320 and

PIC18F1220/2220/4220)

Analog Features:

• 10-bit Analog-to-Digital Converter module (A/D) with:

– Fast sampling rate

– Up to 16 channels input multiplexor

– Conversion available during SLEEP

– DNL = ±1 LSb, INL = ±1 LSb
