For Embedded Computing
The Intel® 845 chipset is designed, validated, and optimized for the Intel® Pentium® 4 processor with Intel NetBurst® micro-architecture using proven and established building blocks. Intel 845 chipset-based platforms extend the Intel Pentium 4 processor capabilities with a great balance of price and performance for embedded computing segments.

The Intel 845 chipset consists of two controller hubs: the 82845 Memory Controller Hub (MCH), which supports a 400 MHz system bus, PC133 SDRAM memory or DDR200/266 memory and the latest graphics devices through the 1.5V AGP4X interface, and the 82801BA I/O Controller Hub (ICH2), which makes a direct connection to the graphics and memory for faster access to peripherals. The ICH2 provides the features and bandwidth required for embedded computing usage models, and is already one of the highest volume PC platform products in the world, supporting motherboards based on the Intel® 815, Intel® 810, and Intel® 850 chipsets.

Drivers for this chipset are available for download.

Product Highlights
Designed, validated, and optimized for the Intel Pentium 4 processor with Intel NetBurst® micro-architecture using proven and established building blocks
400 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 ensure long-term system reliability over wide operating conditions
The AGP4X interface continues to provide the most advanced graphics support available, enabling over 1 GB/s of graphics bandwidth
Two USB controllers provide high-performance peripherals with 24 Mbps of bandwidth, while enabling support for up to four USB ports. This results in a significant increase over previous integrated 1-4 port hubs at 12 Mbps
The latest AC'97 implementation delivers six channels of 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 home phone line, 10/100 Mbps Ethernet, and 10/100 Mbps 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
