Temperature Sensor 
The 6HDD SATA HSBP provides a National* LM75 or equivalent temperature sensor. The host 
can query the LM75 at any time to read the temperature.  
The temperature sensor has an I
2
C address of 0x90h on Port 0 of the GEM424 controller. 
4.3.2.3.3 
Serial EEPROM 
The 6HDD SATA HSBP provides an Atmel* 24C02 or equivalent serial EEPROM for storing the 
FRU information. The 24C02 EEPROM provides 2048 bits of serial electrically erasable and 
programmable read-only memory. 
The serial EEPROM has an I
2
C address of 0xA6h and resides on Port 1 of the GEM424 
controller.
