COM Express module packs dual-core Xeon CPU

Jan 10, 2008 — by Jonathan Angel — from the LinuxDevices Archive — views

MSC Vertriebs has announced a computer-on-module (COM) that supports Intel's dual-core Xeon processors and runs Linux. The CXE-DX5270 targets demanding applications such as pattern recognition, high-energy physics, and real-time systems, according to the company.

The CXE-DX7520 is available in two different versions, one clocking the Xeon at 2.16GHz, and the other using a low-voltage (LV) version that runs at 1.5GHz. Both offer 4MB of second-level cache, support Intel's VT virtualization technology, and can execute both 32-bit and 64-bit wide instructions, according to MSC.

Unlike most other COM Express modules, the CXE-DX7520 is based on a server chipset — including Intel's E7520 northbridge, from which it obviously takes its name, and the 6300ESB southbridge. The E7520 has dual DDR2-400 memory channels that deliver 6.4GB/second bandwidth, according to Intel.

The CXE-DX7520, however, is not quite all Intel, since its graphics controller comes from Silicon Motion. The Lynx3DM (SM721) controller includes 4MB of VRAM and offers resolutions up to 1280 x 1024.

Two 200-pin DIMM sockets on the module accept up to 4GB of dual-channel DDR2 SDRAM with ECC. The device's bus interfaces — which must be accessed via an application-specific baseboard, as usual for COM Express modules — include PCI Express, PCI, and LPC (low pin count) serial.

Features and specifications cited by MSC Vertriebs for the CXE-DX7520 include:

  • Processor — Intel Xeon clocked at 2.16GHz or Xeon LV clocked at 1.5GHz
  • Memory — up to 4GB of dual-channel DDR2 SDRAM with ECC
  • Display — TFT/CRT interface with 4MB of VRAM, resolutions up to 1280 x 1024 pixels
  • Networking — 10/100/1000 Ethernet
  • Other I/O:
    • 2 x IDE ATA/UDMA 100
    • 2 x SATA-150
    • 4 x USB 2.0

  • Expansion:
    • PCI Express:
      • 2 x 8-lane
      • 1 x 4-lane
      • 1 x 1-lane

    • 32-bit PCI
    • LPC bus interface

  • Power requirements — 12V @ 60W typical

  • Operating temperature — 0 to 55 deg. C
  • Dimensions — 6 x 4.3 x 0.5 inches (155 x 110 x 13mm)

For evaluation and development support, a carrier board for the module is available, featuring PCI slots and standard PC interfaces including USB ports. In addition to Linux, the CXE-DX7520 runs Windows XP Embedded, according to MSC.
