PIC24F16KL402 FAMILY

23.2 Unique ID

A read-only Unique ID value is stored at addresses,

800802h through 800808h. This factory programmed

value is unique to each microcontroller produced in the

PIC24F16KL402 family. To access this region, use

table read instructions or Program Space Visibility.

To ensure a globally Unique ID across other Microchip

microcontroller families, the “Unique ID” value should

be further concatenated with the family and Device ID

values stored at address, FF0000h.
