Intel® 3100 Chipset
for Intel® Core™2 Duo Processors, Intel® Core™ Duo Processors and Intel® Celeron® M Processors on 65nm for Embedded Computing
 
Intel® 3100 Chipset The Intel® 3100 Chipset combines server-class memory and I/O controller functions into a single component, creating the first integrated Intel® chipset specifically optimized for embedded, communications, and storage applications. This single-chip system controller replaces a separate memory controller hub and I/O controller hub, significantly conserving board real estate and power consumption.
The Intel 3100 chipset supports the following processors, addressing the needs of high-performance, low-power platforms within small form factor designs such as PrAMC, Compact PCI* and COM Express*:
  • Intel® Core™2 Duo processor L7400Δ with 667 MHz front-side bus (FSB) and thermal design power (TDP) of 17W
  • Intel® Core™2 Duo processor U7500Δ with 533 MHz front-side bus (FSB) and thermal design power (TDP) of 10W
  • Intel® Core™ Duo processor ULV U2500Δ with 533 MHz FSB and TDP of 9W
  • Intel® Celeron® M processor ULV 423Δ with 533 MHz FSB and TDP of 5.5W

Features and benefits
 
Supports Intel® Core™2 Duo processors L7400Δ, U7500Δ and Intel® Core™ Duo processor ULV U2500Δ Two high-performance cores per platform meet the needs of high-performance, low-power applications with small form-factor constraints

Intel® Core™2 Duo processor offers additional performance improvement with Intel® 64 architecture¹, 36 bits of physical address and SSE3 instruction
Supports Intel® Celeron® M processor ULV 423Δ Single-core solution offers scalable performance and value
40 mm x 40 mm FC-BGA package Requires 50% less board space than prior-generation two-chip chipsets²
PCI Express* Direct connection between the Intel® 3100 chipset and PCI Express* component/adapters; bandwidth up to 4 GB/s on the x8 PCI Express interface; higher bandwidth and less I/O bottlenecks than PCI-X*
DDR2-400 memory interface
Maximum memory bandwidth of 3.2 GB/s
Decreased power consumption - especially important on dense rack, hot-plug controller and blade configurations
Advanced Platform RAS
Memory ECC, SEC/DED, and DIMM scrubbing can improve system reliability
32-bit ECRC on PCI Express
Hot swap PCI Express enhances serviceability

¹ 64-bit computing on Intel architecture requires a computer system with a processor, chipset, BIOS, operating system, device drivers and applications enabled for Intel® 64 architecture. Processors will not operate (including 32-bit operation) without an Intel® 64 architecture-enabled BIOS. Performance will vary depending on your hardware and software configurations. Consult with your system vendor for more information.
