DS39616D-page 13 PIC18F2331/2431/4331/4431 1.3 Details on Individual Family Members Devices in the PIC18F2331/2431/4331/4431 family are available in 28-pin (PIC18F2331/2431) and 40/44-pin (PIC18F4331/4431) packages. The block diagram for the two groups is shown in Figure 1-1. The devices are differentiated from each other in three ways: 1. Flash program memory (8 Kbytes for PIC18F2331/4331 devices, 16 Kbytes for PIC18F2431/4431). 2. A/D channels (5 for PIC18F2331/2431 devices, 9 for PIC18F4331/4431 devices). 3. I/O ports (3 bidirectional ports on PIC18F2331/ 2431 devices, 5 bidirectional ports on PIC18F4331/4431 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. Like all Microchip PIC18 devices, members of the PIC18F2331/2431/4331/4431 family are available as both standard and low-voltage devices. Standard devices with Enhanced Flash memory, designated with an “F” in the part number (such as PIC18F2331), accommodate an operating VDD range of 4.2V to 5.5V. Low-voltage parts, designated by “LF” (such as PIC18LF2331), function over an extended VDD range of 2.0V to 5.5V.
