PIC18F2220/2320/4220/4320
1.3 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.
The devices are differentiated from each other in five
ways:
1. Flash program memory (4 Kbytes for
PIC18FX220 devices, 8 Kbytes for PIC18FX320)
2. A/D channels (10 for PIC18F2X20 devices, 13 for
PIC18F4X20 devices)
3. I/O ports (3 bidirectional ports and 1 input only
port on PIC18F2X20 devices, 5 bidirectional
ports on PIC18F4X20 devices)
4. CCP and Enhanced CCP implementation
(PIC18F2X20 devices have 2 standard CCP
modules, PIC18F4X20 devices have one
standard CCP module and one ECCP module)
5. Parallel Slave Port (present only on
PIC18F4X20 devices)
All other features for devices in this family are identical.
These are summarized in Table 1-1.
The pinouts for all devices are listed in Table 1-2 and
Table 1-3.
