6.1.1.1 I

C Serial Bus Interface

The VSC410* controller supports four independent I

C interfaces with bus speed of up to 400

Kbits. The I

C bus 0 supports an AT24C64* EEPROM or equivalent I

C -based EEPROM used

as FRU. The I

C bus 1 supports a TI TMP75* or equivalent I

C -based temperature sensor. This

enables actual temperature value readings to be returned to the host. The Intelligent Platform

Management Bus (IPMB) is supported through the I

C port 2. The SCSI Enclosure Service

(SES) interface is supported through the I

C port 3.

The following figure provides a block diagram of I

C bus connection implemented on the 4HDD

and 6HDD passive SAS/SATA HSBP.
