Details on Individual Family
Members
All other features for devices in this family are identical.
These are summarized in
The pinouts for all devices are listed in
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 V
DD
range of 4.2V to 5.5V.
Low-voltage parts, designated by “LF” (such as
PIC18LF2331), function over an extended V
DD
range
of 2.0V to 5.5V.
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
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).
A/D channels (5 for PIC18F2331/2431 devices,
9 for PIC18F4331/4431 devices).
I/O ports (3 bidirectional ports on PIC18F2331/
2431 devices, 5 bidirectional ports on
PIC18F4331/4431 devices).
