2.3 Device Information Area (DIA)
The Device Information Area (DIA) is a dedicated region in the Program Flash Memory. The data is mapped from address 8100h to 813Fh. These locations are read-only and cannot be erased or modified. The DIA contains the Microchip Unique Identifier words and the Fixed Voltage Reference (FVR) voltage readings in millivolts (mV). The table below holds the DIA information for the PIC16F152XX family of microcontrollers.
