bit 7

bit 0

Legend:

R = Readable bit

P = Programmable bit

U = Unimplemented bit, read as ‘0’

-n = Value when device is unprogrammed

U = Unchanged from programmed state

bit 7-5

DEV<2:0>:

Device ID bits

These bits are used with the DEV<10:3> bits in the Device ID Register 2 to identify the part number.

100

= PIC18F2331

101

= PIC18F2431

bit 4-0

REV<4:0>:

Revision ID bits

These bits are used to indicate the device revision.

DEV<10:3>:

Device ID bits(1)

These bits are used with the DEV<2:0> bits in the Device ID Register 1 to identify the

part number

0000 0101

= PIC18F2331/2431/4331/4431 devices

Note 1:

These values for DEV<10:3> may be shared with other devices. The specific device is always identified by

using the entire DEV<10:0> bit sequence.
