Intel® 845GV Chipset

The Intel® 845GV Chipset-based platform extends the Intel® Pentium® 4 processor capabilities with integrated graphics while maintaining a balance of price and performance for embedded computing segments.

The Intel 845GV Chipset consists of two controller hubs. The 82845GV Memory Controller Hub (GMCH) supports a 400 MHz or 533 MHz system bus, DDR266/200 or PC133 SDRAM memory, and the latest integrated graphics support. The Intel® 82801DB I/O Controller Hub (Intel® ICH4) makes a direct connection to the graphics and memory for faster access to peripherals. It provides the features and bandwidth required for embedded computing-usage models.

Product highlights

  • The Intel 845GV Chipset is designed, validated, and optimized for the Intel Pentium 4 processor with Intel NetBurst® microarchitecture
  • 400 MHz or 533 MHz system bus delivers a high-bandwidth connection between the Intel Pentium 4 processor and the platform, providing 3x the bandwidth over platforms based on Intel® Pentium® III processors
  • Advanced packaging technology and industry leading electrical design innovations deliver long-term system reliability over wide operating conditions
  • Three USB host controllers provide high performance peripherals with 480 Mbps of bandwidth, while enabling support for up to six USB 2.0 ports. This results in a significant increase over previous integrated 1–4 port hubs at 12 Mbps
  • The latest AC’97 implementation delivers 20-bit audio for enhanced sound quality and full surround sound capability. Integrated audio solutions continue to enjoy success as a very cost-effective, yet high-performance solution
  • LAN connect interface (LCI) provides flexible network solutions such as 10/100 Mbps Ethernet and 10/100 Mbps Ethernet with LAN manageability
