Microchip Technology PIC18F8680-E/PT

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):

• Address capability of up to 2 Mbytes
• 16-bit interface

Peripheral Features:

• High current sink/source 25 mA/25 mA
• Four external interrupt pins
• Timer0 module: 8-bit/16-bit timer/counter
