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
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.
