The Intel
815 Chipset Family
Figure 1 shows a typical system block diagram based on the Intel
815 chipset family. The chipset uses a
hub architecture with the GMCH as the host bridge hub and the I/O Controller Hub as the I/O hub. The
GMCH supports processor bus frequencies of 66/100/133 MHz. The I/O Controller Hub is highly
integrated providing many of the functions needed in today’s PC platforms; it also provides the interface
to the PCI Bus. The GMCH and I/O Controller Hub communicate over a dedicated hub interface.
82801AA ICH and 82801BA ICH2 functions include:
PCI Rev 2.2 compliant with support for 33 MHz PCI operations
Supports up to 6 Req/Gnt pairs (PCI Slots)
Power management logic support
Enhanced DMA controller, interrupt controller, and timer functions
Integrated IDE controller
Ultra ATA/66/33 (ICH)
Ultra ATA/100/66/33 (ICH2)
USB host interface
1 host controller and supports 2 USB ports (ICH)
2 host controllers and supports 4 USB ports (ICH2)
Integrated LAN controller (ICH2 only)
System Management Bus (SMBus) compatible with most I
2
C devices
ICH has bus master capability
ICH2 has both bus master and slave capability
AC’97 2.1 compliant link for audio and telephony codecs
2 channels (ICH)
Up to 6 channels (ICH2)
Low Pin Count (LPC) interface
Firmware Hub (FWH) interface support
Intel’s FWH component is the 82802: It contains a Random Number Generator (RNG), five
General Purpose Inputs (GPIs), register-based block locking, hardware-based locking, and
Flash memory for platform code/data nonvolatile storage
FWH component is also available from other suppliers
