DEVICE OVERVIEW

This document contains device specific information for the following devices:

? PIC18F6585 ? PIC18F8585

? PIC18F6680 ? PIC18F8680

PIC18F6X8X devices are available in 64-pin TQFP and 68-pin PLCC packages. PIC18F8X8X devices are available in the 80-pin TQFP package. They are differentiated from each other in four ways:

1. Flash program memory (48 Kbytes for PIC18FX585 devices, 64 Kbytes for PIC18FX680)

2. A/D channels (12 for PIC18F6X8X devices, 16 for PIC18F8X8X)

3. I/O ports (7 on PIC18F6X8X devices, 9 on PIC18F8X8X)

4. External program memory interface (present only on PIC18F8X8X devices)

High-Performance RISC CPU:

? Source code compatible with the PIC16 and PIC17 instruction sets

? Linear program memory addressing to 2 Mbytes

? Linear data memory addressing to 4096 bytes

? 1 Kbyte of data EEPROM

? Up to 10 MIPs operation:

- DC – 40 MHz osc./clock input

- 4 MHz-10 MHz osc./clock input with PLL active

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

? Priority levels for interrupts

? 31-level, software accessible hardware stack

? 8 x 8 Single-Cycle Hardware Multiplier

External Memory Interface (PIC18F8X8X Devices Only):
