Unique ID
The MCP7940X features an additional 64-bit unique ID
area.
The unique ID is located at addresses 0xF0 through
0xF7. Reading the unique ID requires the user to
simply address these bytes.
The unique ID area is protected to prevent unintended
writes to these locations. The unlock sequence is
detailed in Section 5.2.1 “Unlock Sequence”.
The unique ID can be factory programmed on some
devices to provide a unique IEEE EUI-48 or EUI-64
value. In addition, customer-provided codes can also
be programmed.
