Details on Individual Family

Members

The PIC18F6X2X/8X2X devices are available in 64-pin

and 80-pin packages. They are differentiated from

each other in four ways:

FLASH

program

memory

(48 Kbytes

for

PIC18FX525

devices

and

64 Kbytes

for

PIC18FX621 devices)

A/D channels (12 for PIC18F6X2X devices,

16 for PIC18F8X2X)

I/O ports (7 on PIC18F6X2X devices, 9 on

PIC18F8X2X)

External program memory interface (present

only on PIC18F8X2X devices)

All other features for devices in the PIC18F6X2X/8X2X

family

are identical. These are summarized

Table 1-1.

Block diagrams of the PIC18F6X2X and PIC18F8X2X

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

respectively. The pinouts for these device families are

listed in Table 1-2.
