unique IDnumber for microcontroller

[ismu]

is ther any unique ID number for each dsPIC ,
assume i have 5 numbers of dsPIC30F2010 , i want to know is any diff identification number for each?

Device ID (DEVID) Registers
Configuration memory space locations 0xFF0000 and 0xFF0002 are used to store a read-only
Device ID number that is set when the device is manufactured. This number identifies the
dsPIC33F device type and the silicon revision.
The Device ID registers can be read using table read instructions.

thanks Yura

dspic30f series have this same DEVID register.so my doubt is

1- whether this ID is different for each pic ?
i mean i have one dspic30f2010 and you have the same chip. so after mixing this both chip ,can you distinguish which one is yours[both are blank] by using this DEVID register reading cmd ?

2-i could see about UNITID register ,what about this one?

3-in 16f73 one "ID Locations" location is there this is read/write type and we cannot access at exicution time, but at the time of manufacturing this is 0 for all device .

Unit ID Field
The Unit ID field is located at configuration memory space locations 0xF80010 through 0xf80016.
This field consists of four configuration registers (FUID0-FUID3) and can be programmed with
unique device information

Can you tell the answer for prevous question 1.

question #1 ... just number is similar USB ID manufacture ... all microchips will have same number.
