PIC18F1220/1320
1.3 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.
