cPCI board offers Core i7 CPUs, ruggedization options

Nov 1, 2010 — by Eric Brown — from the LinuxDevices Archive — 2 views

Extreme Engineering Solutions (X-ES) is shipping a conduction- or air-cooled 6U CompactPCI single board computer (SBC) based on the Intel Core i7 processor. The XCalibur4301 offers up to 16GB of DDR3 SDRAM, three gigabit Ethernet ports, thee USB 2.0 ports, dual DVI ports, plus a choice of three levels of ruggedization.

The XCalibur4301 targets upgrades to existing commercial, industrial, and military 6U CompactPCI applications, says X-ES. Board support packages are offered for Linux, VxWorks, QNX Neutrino, and Integrity. Windows drivers are also available, says the company.

In September, X-ES announced a 3U CompactPCI (cPCI) board based on a Freescale QorIQ P4080 system-on-chip (SoC), called the XPedite5430. The company's latest cPCI board instead opts for the Intel Core i7, the most powerful of a number of embedded, 32nm-fabricated Core processors Intel announced in January. (Other recent 6U cPCI boards equipped with the Core i7 include the Adlink cPCI-6510 and the Kontron CP6002.)

The XCalibur4301 offers a choice of dual-core Intel Core i7 processors, including the i7-610E (2.53GHz), -620LE (2.0GHz), and -620UE (1.06GHz). Each is equipped with hyper-threading technology, and matched with an Intel QM57 chipset. Up to 16GB of DDR3-1066 ECC SDRAM is said to be supported via dual 8GB channels.

The XCalibur4301 is equipped with a cPCI site supporting PICMG 2.1, 2.3, 2.9, and 2.16 standards. Also available is a PMC site and a XMC site (see block diagram and spec list farther below).

Three gigabit Ethernet ports and three USB 2.0 ports are provided, in each case with one of the ports facing front, says X-ES. Other I/O includes I2C and SATA, as well as dual DVI ports, one of which is front-facing and appears to be configured as an HDMI port.

Three levels of ruggedization are available, with different levels of temperature, shock, and vibration resistance. The highest level offers support for operating temperatures of -40 to 185 deg. F (-40 to 85 deg. C), says the company.
