REV4 REV3 REV2 REV1 REV0
bit 7 bit 0
Legend:
R = Read-only bit
-n = Value when device is unprogrammed
U = Unimplemented bit, read as ‘0’
u = Unchanged from programmed state
bit 7-5 DEV<2:0>: Device ID bits
011 = PIC18LF4XJ10
010 = PIC18LF2XJ10
001 = PIC18F4XJ10
000 = PIC18F2XJ10
bit 4-0 REV<4:0>: Revision ID bits
These bits are used to indicate the device revision.
Note 1: Where values for DEV<2:0> are shared by more than one device number, the specific device is always
identified by using the entire DEV<10:0> bit sequence.

bit 7-0 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.
0001 1100 = PIC18FX5J10 devices
0001 1101 = PIC18FX4J10 devices
Note 1: The values for DEV<10:3> may be shared with other device families. The specific device is always
identified by using the entire DEV<10:0> bit sequence.
