DEVICE OVERVIEW

This document contains device specific information for

the following devices:

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:

Flash program memory (48 Kbytes for

PIC18FX585 devices, 64 Kbytes for

PIC18FX680)

A/D channels (12 for PIC18F6X8X devices,

16 for PIC18F8X8X)

I/O ports (7 on PIC18F6X8X devices, 9 on

PIC18F8X8X)

External program memory interface (present

only on PIC18F8X8X devices)

All

other

features

for

devices

the

PIC18F6585/8585/6680/8680

family

are

identical.

These are summarized in Table 1-1.

Block diagrams of the PIC18F6X8X and PIC18F8X8X

devices are provided in Figure 1-1 and Figure 1-2,

respectively. The pinouts for these device families are

listed in Table 1-2.
