C8051F50x/F51x
11.4. Serial Number Special Function Registers (SFRs)
The C8051F50x/F51x devices include four SFRs, SN0 through SN3, that are pre-programmed during pro-
duction with a unique, 32-bit serial number. The serial number provides a unique identification number for
each device and can be read from the application firmware. If the serial number is not used in the applica-
tion, these four registers can be used as general purpose SFRs.
SFR Definition 11.7. SNn: Serial Number n
SFR Addresses: SN0 = 0xF9; SN1 = 0xFA; SN2 = 0xFB; SN3 = 0xFC; SFR Page = 0x0F;
