DEV2:DEV0: Device ID bits

000 = PIC18F4520

010 = PIC18F4420

100 = PIC18F2520

110 = PIC18F2420

REV4:REV0: Revision ID bits

These bits are used to indicate the device revision.

Legend:

R = Read-only bit

P = Programmable bit

-n = Value when device is unprogrammed

U = Unimplemented bit, read as ‘0’

u = Unchanged from programmed state

DEV10:DEV3: Device ID bits

These bits are used with the DEV2:DEV0 bits in the Device ID Register 1 to identify the

part number.

0000 1100 = PIC18F2420/2520/4420/4520 devices

Note: These values for DEV10:DEV3 may be shared with other devices. The specific

device is always identified by using the entire DEV10:DEV0 bit sequence.

R = Read-only bit

P = Programmable bit

-n = Value when device is unprogrammed

U = Unimplemented bit, read as ‘0’

u = Unchanged from programmed state
