Product Details

The Intel®631xESB/632xESB I/O Controller Hub component integrates bridge functionality for PCI Express, PCI-X, conventional PCI, LPC, USB, SATA, IDE and SMBus, and dual-Gigabit ethernet MAC components as well as numerous board management functions. It provides for all system I/O, allowing for simpler system board architectures and smaller board areas than if discrete components were used. Thus, the Intel®631xESB/632xESB I/O Controller Hub provides extensive I/O support. Functions and capabilities include:

  • Enterprise South Bridge Interface (ESI) and PCI Express X8 upstream ports to Memory Controller Hub (MCH)
  • PCI Express Specification, Revision 1.0a-compliant
  • PCI Protocol Addendum and PCI Electrical and Mechanical Addendum to the PCI Local Bus Specification,Revision 2.0a-compliant
  • PCI Local Bus Specification, Revision 2.3-compliant with support for 33 MHz PCI operations (supports up to seven Req/Gnt pairs)
  • ACPI power management logic support
  • Enhanced DMA controller, interrupt controller, and timer functions
  • Integrated serial ATA host controller with independent DMA operation on six ports and AHCI support
  • Integrated IDE controller supports Ultra ATA100/66/33
  • USB host interface with support for eight USB ports; four UHCI host controllers; one EHCI high-speed USB 2.0 Host controller Dual Gigabit MAC with
  • Kumeran interface to dual-PHY component
  • PICMG-compliant Serdes backplane Gigabit Ethernet support
  • Integrated Board Management Controller with basic ROM firmware, expandability through external flash and RAM memories
  • System Management Bus (SMBus) Specification, Version 2.0-compliant with additional support for I2C* devices
  • Audio interface (AC’97 and Intel® High Definition Audio)
  • Low Pin Count (LPC) interface
  • Firmware Hub (FWH) interface support

The Intel®631xESB/632xESB I/O Controller Hub incorporates a variety of PCI functions that are divided into several logical devices (Bm:D0, B0:D28, B0:D29, B0:D30, B0:D31, Bn:D0, Bp:D0, Bp:D1 and Bp:D3). Bm:D0 is the PCI Express upstream port-to-PCI-X bridge, D28 contains the PCI Express root ports, D30 is the ESI-to-PCI bridge, D31 contains the PCI-to-LPC bridge, IDE controller, SATA controller, SMBus controller and the AC ‘97 Audio and Modem controller functions, and D29 contains the four USB UHCI controllers and one USB EHCI controller. Bn:D0 is the integrated LAN controller and MACs. Bp:D0, Bp:D1 and Bp:D3 are PECI express downstream ports.
