The CPU-71-10 is a VMEbus (and VME64) compatible platform based on either the Intel® low-power Core-Duo (Yonah) processor or the Intel® Core™2 Duo Mobile Processor L7400. The CPU-71-10 takes advantage of the Core-Duo’s low 15 W power consumption (Core 2 Duo at 17W)as a rugged Single Board Computer (SBC). It is optionally available as an IEEE 1101.2-compliant, conduction-cooled VMEbus module with wedge locks and a full-board heat sink for high shock/vibration environments and temperature extremes.

The E7520 Memory Controller Hub (MCH) and 6300ESB I/O Controller Hub (ICH) chipset supports PCI-X and PCIe expansion, USB 2.0, ATA/100, and Serial ATA (SATA). Two Gb Ethernet ports and two USB 2.0 ports are accessible from the front panel in addition to two PMC bezels. On-board CompactFlash permits single-slot booting. Two VITA 31.1-compliant, 10/100/1000BaseTX ports are routed to the backplane. Two SATA ports, VGA video, two Gb Ethernet ports, four RS232 ports, one RS422 port, an IDE interface, PS/2 mouse & keyboard, and two more USB 2.0 ports are routed to the backplane. Two PMC-X site is provided for additional I/O expansion. Conventional PC I/O is accessible with industry-standard connectors on optional rear I/O modules.

Core2 Duo Mobile Processor L7400
Delivering breakthrough energy efficient performance for embedded platforms. 65 nm process technology makes it possible to integrate two complete execution cores in one physical package, providing advancements in simultaneous computing for multi-threaded applications and multitasking environments. While incorporating advanced processor technology this processor remains software compatible with previous IA-32 processors. Executes four instructions per cycle to improve execution speed and efficiency using 14-stage pipeline. Supports 64-bit instructions, providing flexibility for 64-bit and 32-bit applications and operating systems.
E7520 Memory Controller Hub
The Intel E7520 chipset acts as the central hub for all data passing between the core system elements including processor, memory, PCI Express I/O, and legacy I/O subsystems. The Intel® E7520 chipset enables a variety of high-performance, low-power designs with improved platform reliability and system manageability. This chipset utilizes revolutionary PCI Express1 serial I/O technology and next-generation DDR2 memory technology to help increase I/O bandwidth and reduce system latency for data-intensive applications. The 533 MHz bus allows this chipset to support Intel® Core-Duo processors.
6300ESB I/O Controller Hub
The Intel® 6300ESB I/O Controller Hub (ICH) supports legacy and more cutting edge I/O. It is designed for use with the Intel® E7520 Memory Controller Hub (MCH). Intel has integrated features into the 6300ESB ICH that offer the performance, stability and reliability customers require for embedded computing applications. It improves bandwidth via PCI-X 64/66 and PCI 32/33 support. It also provides port 60/64 emulation, dual UARTs, four USB 2.0 ports, two SATA ports, primary and secondary IDE, and a two-stage watchdog timer. The Intel 6300ESB ICH and associated drivers help reduce support and validation costs.
The CPU-71-10 supports 2 or 4 GBytes of DRAM and its DDR2-400 memory technology is ideal for memory-intensive applications, providing up to 20 percent increase in memory bandwidth, and up to 40 percent decrease in power consumption over DDR 266 memory. The memory subsystem interface to E7520 is dual channel, supporting two registered DIMMs per channel—depending on memory technology—for a total system bandwidth of up to 6.4 GB/second. ECC error correction is supported.
Four Gb Ethernet Ports
Two are accessible from the front panel while the other two are routed to the P0 connector in compliance with Vita 31.1. The CPU-71-10 gets its four Ethernet ports from two Intel® 82571EB Gigabit Ethernet Controllers. The 82571EB provides two fully integrated Gigabit Ethernet Media Access Control (MAC) and physical layer (PHY) ports. This device uses the PCI Express architecture (Rev. 1.0a) as a host interface. The Intel 82571EB supports Ethernet interfaces for 1000BASE-T, 100BASE-TX, and 10BASE-T applications. In addition to managing MAC and PHY Ethernet layer functions, the controller manages PCI Express packet traffic across its transaction, link, and physical/logical layers.
