24.4 Device Identification Registers
The dsPIC30F devices have two sets of registers located in configuration space that provide
identification information.
24.4.1 Device ID (DEVID) Registers
The 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
dsPIC30F device type and the silicon revision.
The Device ID registers can be read by the user using table read instructions.
24.4.2 Unit ID Field
The Unit ID field is located at configuration memory space locations 0x800600 through
0x80063E. This field consists of 32 program memory locations and can be programmed at the
Microchip factory with unique device information. This field cannot be written or erased by the
user, but can be read using table read instructions.
Please contact Microchip technical support or your local Microchip representative for further
details.
