6.1.1.3 Temperature Sensor
The 4HDD and 6HDD passive SAS/SATA HSBP provides a TI TMP75* or equivalent
temperature sensor. The host can query the TMP75* at any time to read the temperature.
The temperature sensor has an I
2
C address of 0x90h on Port 1 of the VSC410* controller.
6.1.1.4 Serial EEPROM
The 4HDD and 6HDD SAS/SATA HSBP provides an Atmel AT24C64* or equivalent serial
EEPROM for storing the FRU information. The AT24C64* EEPROM provides 64K bits of serial
electrically erasable and programmable read-only memory.
The serial EEPROM has an I
2
C address of 0xA0h and resides on Port 0 of the VSC410*
controller.
