Details on Individual Family

Members

Devices in the PIC18F1220/1320 family are available

in 18-pin, 20-pin and 28-pin packages. A block diagram

for this device family is shown in Figure 1-1.

The devices are differentiated from each other only in

the amount of on-chip Flash program memory

(4 Kbytes for the PIC18F1220 device, 8 Kbytes for the

PIC18F1320 device). These and other features are

summarized in Table 1-1.

A block diagram of the PIC18F1220/1320 device

architecture is provided in Figure 1-1. The pinouts for

this device family are listed in Table 1-2.
