PIC24FJ128GA106 Microcontroller Unique ID

[Vinod.k]

Hi,

I am not able to find the microcontroller id in PIC24FJ128GA106. Please, anyone, help me how to read the microcontroller unique id.
Is this controller has a microcontroller unique id?

Thank you,
Vinod Kumar

Depends on exactly what you mean by Unique ID.

Do you mean something that identifies the part specifically as a PIC23FJ128GA106? If so you're looking for the DEVID register, which is on page 252 of the datasheet:

If you're looking for something like a Serial Number that is unique to every IC, I'm afraid you may be out out of luck. You can buy serial number ICs though if you need a serial number. I've used this one before:

IIRC the PicKit3 has some trick that it can use to include a unique serial number when used as a stand-alone programmer.
I could be very wrong but search for something along those lines.
