Chapter 23. Package Information
Chapter 23 provides drawings of the physical dimensions and characteristics of the 609-mBGA
package.
Chapter 24. Testability
Chapter 24 provides detail about the implementation of test modes provided in the ICH6.
Overview
The ICH6 provides extensive I/O support. Functions and capabilities include:
• PCI Express* Base Specification, Revision 1.0a-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 four ports
(ICH6/ICH6R only) or two ports (ICH6-M only) and AHCI support (ICH6R/ICH6-M only).
• 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
• Integrated LAN controller
• System Management Bus (SMBus) Specification, Version 2.0 with additional support for I²C
devices
• Supports Audio Codec ’97, Revision 2.3 Specification (a.k.a., AC ’97 Component
Specification, Revision 2.3) which provides a link for Audio and Telephony codecs (up to 7
channels)
• Supports Intel High Definition Audio
• Low Pin Count (LPC) interface
• Firmware Hub (FWH) interface support
The ICH6 incorporates a variety of PCI functions that are divided into six logical devices (B0:D27,
B0:D28, B0:D29, B0:D30, B0:D31 and B1:D8). D30 is the DMI-to-PCI bridge and the AC ’97
Audio and Modem controller functions, D31 contains the PCI-to-LPC bridge, IDE controller,
SATA controller, and SMBus controller, D29 contains the four USB UHCI controllers and one
USB EHCI controller, and D27 contains the PCI Express root ports. B1:D8 is the integrated LAN
controller.
