PIC18F2331/2431/4331/4431  
All other features for devices in this family are identical.  
These are summarized in Table 1-1.  
1.3  
Details on Individual Family  
Members  
The pinouts for all devices are listed in Table 1-2 and  
Table 1-3.  
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.  
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.  
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).
