Intel® Server Board SE7210TP1-E TPS
Functional Architecture
3.2.5
SMBus Interface
The SMBus interface can be used for system and power management related tasks. The
interface is compliant with System Management Bus Specification Revision 2.0. The SMBus
interface allows full read/write access to all configuration and memory spaces in the FWH.
3.2.6
6300ESB I/O Controller Hub
The 6300ESB I/O is a multi-function device providing an upstream hub interface for access to
several embedded I/O functions and features including:
• PCI Local Bus Specification, Revision 2.2 with support for 33 MHz PCI operations
and 66 MHz PCI-X operations.
• ACPI power management logic support
• Enhanced DMA controller, interrupt controller, and timer functions
• Integrated IDE controller with support for Ultra ATA100/66/33
• Integrated SATA controller
• USB host interface with support for four USB ports; two UHCI host controllers; one
EHCI high-speed USB 2.0 host controller
• System Management Bus (SMBus) Specification, Version 2.0 with additional support
for I2C devices
• Low Pin Count (LPC) interface
• Firmware Hub (FWH) interface support
Each function within the 6300ESB has its own set of configuration registers. Once configured,
each appears to the system as a distinct hardware controller sharing the same PCI bus
interface.
Performance Note: The Hub Link 1.5 interface between the 6300ESB ICH and the 827210
MCH has a theoretical maximum throughput of 266MB/s. Each bus supported by the 6300ESB
ICH will share the Hub Link 1.5 bandwidth, this includes the P64-A bus, the P32-A bus, the
BMC interface, the LPC bus, the USB 2.0 interface, the Parallel ATA bus and the Serial ATA
bus.
3.2.7
PCI Interface
The 6300ESB I/O PCI interface provides a 33 MHz, Revision 2.3 compliant implementation. All
PCI signals are 5-V tolerant, except PME#. The 6300ESB I/O integrates a PCI arbiter that
supports up to four external PCI bus masters in addition to the internal 6300ESB I/O requests.
On the SE7210TP1-E server board this PCI interface is used to support on-board PCI devices
including the ATI* video controller.
