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® micro-architecture 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 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 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® micro-architecture 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
