9.1.3.1 Microchip Unique Identifier (MUI)
The PIC16F152 devices are individually encoded during
final manufacturing with a Microchip Unique Identifier (MUI). The MUI cannot be erased
by a Bulk Erase command or any other user-accessible means. This feature allows for
manufacturing traceability of Microchip Technology devices in applications where this is
required. It may also be used by the application manufacturer for a number of functions
that require unverified unique identification, such as:
- Tracking the device
- Unique serial number
The MUI consists of nine program words. When taken together,
these fields form a unique identifier. The MUI is stored in read-only locations, located
between 8100h to 8108h in the DIA space. The DIA Table lists
the addresses of the identifier words.
Important: For applications requiring verified
unique identification, contact the Microchip Technology sales office to create a
serialized quick turn programming option.
