4.3.3.3 Temperature Sensor
The 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.
4.3.3.4 Serial EEPROM
The 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.
