14.4. 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—C8051F990
0xD1—C8051F991
0xD6—C8051F996
0xD2—C8051F997

0xD3—C8051F980
0xD4—C8051F981
0xD5—C8051F982
0xD7—C8051F983
0xD8—C8051F985
0xD9—C8051F986
0xDA—C8051F987
0xDB—C8051F988
0xDC—C8051F989
