Unique Device Identifier (UDID)
All dsPIC33EPXXXGS70X/80X family devices are
individually encoded during final manufacturing with
a Unique Device Identifier or UDID. This feature
allows for manufacturing traceability of Microchip
Technology devices in applications where this is a
requirement. It may also be used by the application
manufacturer for any number of things that may
require unique identification, such as:
• Tracking the device
• Unique serial number
• Unique security key
The UDID comprises five 24-bit program words.
When taken together, these fields form a unique
120-bit identifier.
The UDID is stored in five read-only locations,
located between 800F00h and 800F08h in the
device configuration space. Table 4-1 lists the
addresses of the identifier words and shows their
contents.
