C602 (-A) Chipset Functional Overview
The following sub-sections provide an overview of the key features and functions of the Intel
®
C602 (-A)
chipset. For more comprehensive chipset specific information, refer to the Intel
®
C600 Series chipset
documents listed in the Reference Document list.
On the Intel
®
Server Board S2400BB, the following chipset features are utilized:
• Low Pin Count (LPC) interface
• Universal Serial Bus (USB) Controller
• PCI Express root ports
• AHCI SATA Controller
• SCU SATA/SAS Controller
• Manageability Features
3.3.1 Low Pin Count (LPC) Interface
The chipset implements an LPC Interface as described in the LPC 1.1Specification and provides support for up
to two Master/DMI devices. On the server board, the LPC interface is utilized as an inter-connect between the
chipset and the Integrated Base Board Management Controller as well as providing support for the optional
Trusted Platform Module (TMP).
3.3.2 Universal Serial Bus (USB) Controller
The chipset has two Enhanced Host Controller Interface (EHCI) host controllers that support USB high-speed
signaling. High-speed USB 2.0 allows data transfers up to 480 Mb/s which is 40 times faster than full-speed
