NH82801GB Integrated Circuit Chip Intel® 945G Express and 945GC Express Chipsets for Embedded Computing

Intel® 945G Express and Intel® 945GC Express Chipsets for Embedded Computing

Product Overview

The Intel® 945G Express and Intel® 945GC Express chipsets deliver innovative features for interactive clients and many other embedded computing solutions requiring enhanced graphics capabilities.

These advancements include dual-channel DDR2-667 memory technology, Intel® Graphics Media Accelerator 950 (Intel® GMA 950), enhanced manageability and storage security technologies with Intel® Active Management Technology1 (Intel® AMT), and Intel® Matrix Storage Technology.

Designed for, and validated with Intel® Pentium® 4 processors 551∆ and 651∆ with Hyper-Threading Technology2 (HT Technology), and Intel® Celeron® D processors 352∆ and 341∆ — all with Intel® 64 Architecture3 — these platforms provide scalable performance and are ideal price/performance solutions for embedded computing applications.

These chipsets consist of a Graphics and Memory Controller Hub (GMCH) and Intel® ICH7/ ICH7R I/O Controller Hub (ICH). They deliver outstanding system performance through high-bandwidth interfaces such as PCI Express* x16 graphics or I/O, PCI Express x1 I/O ports, next-generation Serial ATA (SATA II), and Hi-Speed USB 2.0 connectivity.

The new graphics core, combined with a high-performance dual-channel memory interface, can deliver significant graphics performance over previous Intel® platforms. With support for dual independent display, enhanced modes for widescreen flat panels, and optimized 3D, embedded platforms based on the Intel 945G Express or Intel 945GC Express chipset can deliver an intense, realistic visual experience without requiring a separate graphics card.

Product Highlights

• 533/800/1066 MHz system bus on the Intel 945G Express chipset, and 533/800 MHz system bus on the Intel 945GC Express chipset provide scalability to higher performance Intel Pentium 4 processors with HT Technology and Intel Celeron D processors

• Dual-channel DDR2-400/533/667 delivers up to 10.7 GB/second of bandwidth and 4 GB memory addressability for faster system responsiveness and support for 64-bit computing

• Intel® Flex Memory Technology facilitates easier upgrades by allowing different memory sizes to be populated and remain in dual-channel mode

• Dual independent display support through the integrated Intel GMA 950 graphics engine and sDVO outputs

• PCI Express x16 GFx can deliver up to greater than 3.5 times the bandwidth of previous discrete graphics solutions; PCI Express x16 interface can also operate as x1 general-purpose I/O

• Both ADD2 and Media Expansion Cards (MECs) allow users to take advantage of several video output options (DVI, dual independent display, component, composite, HDTV, and LVDS) in a single-card solution. In addition, MECs enable video input capability and personal video recorder (PVR) functionality, and can support a wide range of display types and configurations.

• Intel Matrix Storage Technology provides protection and faster access to digital photo, video, and data content through RAID 0, 1, 5, and 10

• Advanced Host Controller Interface4 provides native command queuing for faster boot time and file transfers

• Direct Media Interface (DMI) delivers 2.0 GB/second concurrent bandwidth to maximize throughput between the core chipset components

• Six PCI masters provide generous system expansion capability

• ICH7 supports up to four PCI Express ports configurable as one single x4 or four single x1

• ICH7R supports up to six PCI Express ports configurable as one single x4 and two x1 ports, or six x1 ports

• Up to four next-generation SATA II, delivering 3.0 Gb/s of bandwidth each

• Intel AMT enables remote, down-the-wire management of out-of-band networked systems, regardless of system state

• Flexible wired LAN options with or without Intel AMT

• Eight integrated USB 2.0 ports

• Intel® High Definition Audio features eight independent DMA audio engines or AC’97

• Intel® Stable Image Platform support

• Embedded lifecycle support

• Along with a strong ecosystem of hardware and software vendors, including members of the Intel® Embedded and Communications Alliance (intel.com/go/eca), Intel helps cost-effectively meet development challenges and speed time-to-market
