product brief
Intel^® 845E Chipset for
Applied Computing
Product Highlights
s 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
s 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
s Advanced packaging technology and industry-
leading electrical design innovations deliver
long-term system reliability over wide
operating conditions
s The AGP4X interface provides advanced
graphics support, enabling over 1GB/s
of graphics bandwidth
s 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
s 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
s LAN Connect Interface (LCI) provides
flexible network solutions such as
10/100Mbps Ethernet and 10/100Mbps
Ethernet with LAN manageability
s _{The Intel}^® _SingleDriver^™ _{Technology supports}
all three network options, which simplifies
network connectivity and eases deployment
s _{Dual Ultra ATA 100 controllers, coupled}
with the Intel^® Application Accelerator –
a performance software package – support
faster IDE transfers to storage devices
s _{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
s 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
s Embedded lifecycle support
Intel 845E Chipset Overview
Evolutionary Architecture
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 applied
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 applied
computing-usage models.
