18.4. Determining the Device Part Number at Run Time
In many applications, user software may need to determine the MCU part number at run time in order to
determine the hardware capabilities. The part number can be determined by reading the value of the
DEVICEID Special Function Register.
The value of the DEVICEID register can be decoded as follows:
0xD0—C8051F960
0xD1—C8051F961
0xD2—C8051F962
0xD3—C8051F963
0xD4—C8051F964
0xD5—C8051F965
0xD6—C8051F966
0xD7—C8051F967
0xD8—C8051F968

Device Identification.
These bits contain a value that can be decoded to determine the device part
number.
Revision Identification.
These bits contain a value that can be decoded to determine the silicon
revision. For example, 0x00 for Rev A and 0x01 for Rev B, etc.
