AIMB-251 Series
Distributed arbitration for highly concurrent operation
•
Three USB host controllers provide high performance peripherals with 480 Mbps 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 12 Mbps
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 10/100
•
Mbps Ethernet and 10/100 Mbps Ethernet with LAN manageability
Dual Ultra ATA/100 controllers, coupled with the Intel® Application Accelerator – a
•
performance software package – support faster IDE transfers to storage devices
Intel Application Accelerator software provides additional performance over native
•
ATA drivers by improving I/O transfer rates and enabling 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
1.6.4
DRAM Interface (Intel 852GM)
The 852GM GMCH system memory controller directly supports the following:
• One channel of PC1600/2100/2700 DDR SDRAM memory
• DDR SDRAM devices with densities of 128-Mb, 256-Mb, and 512-Mb technology
• Up to 1 GB (512-Mb technology) SDRAM
1.6.5
DRAM Interface (Intel 852GM)
The 852GM GMCH system memory controller directly supports the following:
• One channel of PC1600/2100 DDR SDRAM memory
• DDR SDRAM devices with densities of 128-Mb, 256-Mb, and 512-Mb technology
• Variable page sizes of 2-kB, 4-kB, 8-kB, and 16-kB. Page size is individually selected
for every row and a maximum of 16 pages may be opened simultaneously
1.6.6
PCI Interface
The ICH4 PCI interface provides a 33 MHz, Rev. 2.2 compliant implementation. All PCI
signals are 5V tolerant, except PME#. The ICH2 integrates a PCI arbiter that supports up to
six external PCI bus masters in addition to the internal ICH4 requests.
