PIC18F2220/2320/4220/4320
3. I/O ports (3 bidirectional ports and 1 input only
port on PIC18F2X20 devices, 5 bidirectional
ports on PIC18F4X20 devices)

Details on Individual Family
Members
Devices in the PIC18F2220/2320/4220/4320 family are
available in 28-pin (PIC18F2X20) and 40/44-pin
(PIC18F4X20) packages. Block diagrams for the two
groups are shown in Figure 1-1 and Figure 1-2.
4. CCP and Enhanced CCP implementation
(PIC18F2X20 devices have 2 standard CCP
modules, PIC18F4X20 devices have one
standard CCP module and one ECCP module)
The devices are differentiated from each other in five
ways:
5. Parallel Slave Port (present only on
PIC18F4X20 devices)
1. Flash program memory (4 Kbytes for
PIC18FX220 devices, 8 Kbytes for PIC18FX320)
All other features for devices in this family are identical.
These are summarized in Table 1-1.
2. A/D channels (10 for PIC18F2X20 devices, 13 for
PIC18F4X20 devices)
The pinouts for all devices are listed in Table 1-2 and
Table 1-3.
