Intel® 3100 ChipsetFor Intel® Core™2 Duo processors, Intel® Core™ Duo processors, and Intel® Celeron® M processors on 65nm for embedded computing
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 FSB and 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

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.
