For embedded computing

The Intel® 845E Chipset is designed, validated, and optimized for the Intel® Pentium® 4 processor and Intel® Pentium® 4 processor - M with Intel NetBurst® microarchitecture using proven and established building blocks. Intel 845E Chipset-based platforms extend the Intel Pentium 4 processor and Intel Pentium 4 processor - M capabilities with an excellent balance of price and performance for embedded computing segments.

The Intel 845E Chipset consists of two controller hubs: the Intel® 82845E Memory Controller Hub (MCH) supports a 400MHz or 533MHz system bus, DDR200/266 memory and the latest graphics devices through the 1.5V AGP4X interface. The Intel® 82801DB I/O Controller Hub (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

  • Designed, validated, and optimized for the Intel Pentium 4 processor and Intel Pentium 4 Processor - M with Intel NetBurst microarchitecture using proven and established building blocks
  • 400MHz or 533MHz 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 ensure long term system reliability over wide operating conditions
  • The AGP4X interface continues to provide the most advanced graphics support available, enabling over 1GB/s of graphics bandwidth
  • Three USB controllers provide high performance peripherals with 480Mbps 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 12Mbps
  • 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 10/100Mbps Ethernet and 10/100Mbps Ethernet with LAN manageability
  • The Intel® SingleDriver™ technology supports all three network options, which simplifies network connectivity and eases deployment
  • Dual Ultra ATA/100 controllers, coupled with the Intel® Application Accelerator – a performance software package – support faster IDE transfers to storage devices
  • The Intel Application Accelerator software provides additional performance over native ATA drivers. The Intel Application Accelerator improves system performance by improving I/O transfer rates and enables faster O/S load time resulting in accelerated boot times
  • Communication and Network Riser (CNR) offers flexibility in system configuration with a baseline feature set that can be upgraded with an audio card, modem card, or network card
  • Embedded lifecycle support
