3.1

User ID Location

A user may store identification information (user ID) in

four designated locations. The user ID locations are

mapped to 8000h-8003h. Each location is 14 bits in

length. Code protection has no effect on these memory

locations. Each location may be read with code

protection enabled or disabled.

3.2

Device ID

The device ID word is located at 8006h. This location is

read-only and cannot be erased or modified.

Note:

MPLAB® IDE only displays the 7 Least

Significant bits (LSb) of each user ID

location, the upper bits are not read. It is

recommended that only the 7 LSb’s be

used if MPLAB IDE is the primary tool

used to read these addresses.

Legend:

P = Programmable bit

U = Unimplemented bit, read as ‘0’

R = Readable bit

W = Writable bit

‘0’ = Bit is cleared

-n = Value at POR

‘1’ = Bit is set

x = Bit is unknown

bit 13-5

DEV<8:0>: Device ID bits

These bits are used to identify the part number.

bit 4-0

REV<4:0>: Revision ID bits

These bits are used to identify the revision.
