SMBus/I
The physical address for the TS is different than that used by the EEPROM. The TS physical
address is binary 0 0 1 1 A2 A1 A0 RW, where A2, A1, and A0 are the three slave sub-
address pins, and the LSB “RW” is the READ/WRITE flag.
The EEPROM physical address is binary 1 0 1 0 A2 A1 A0 RW for the memory array and is
0 1 1 0 A2 A1 A0 RW for permanently set write protection mode.
