The Input/Output Controller Hub 2 (82801BA)

The Input/Output Controller Hub 2 (82801BA)

The ICH2 is encapsulated in a 360-pin Enhanced Ball Grid Array (EBGA) package and is located on the system board just underneath the AGP connector. It provides the interface between the PCI bridge (PCI Rev. 2.2 compliant with support for 32-bit 33 MHz PCI operations), PCI-to-LPC (Low Pin Count) bridge, IDE controller, USB controller, SMBus controller and Audio Codec ’97 controller.

The ICH2 functions and capabilities are discussed in detail later on in this section. The following figure shows an example of the system block diagram using the ICH2.
