10 / 388 page PIC18F2220/2320/4220/4320 DS39599C-page 8 2003 Microchip Technology Inc. 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.
