Module snaps 1.6GHz quad-core ARM engine into embedded apps

Mar 29, 2013  |  Rick Lehrbaum

Cogent Computer Systems has introduced a high-end member of its computer-on-module family, based on Marvell’s 1.6GHz quad-core, ARMv7-powered “Armada XP” system-on-chip. The SODIMM-style CSB1726 module packs high-speed SATA and Ethernet ports, PCIe expansion, video, and numerous other I/O ports, and is supported with an embedded Linux BSP.

Cogent says the CSB1726 is well suited for use in Linux-based embedded systems requiring high performance networking and storage.

Cogent lists these features and specifications for its CSB1726 module:

  • Choice of Marvell Armada XP multicore SOCs, based on ARMv6/7 cores:
    • Dual-core MV78260, clocked at 1GHz
    • Quad-core MV78460, clocked at 1.6GHz
  • RAM — 2GB DDR3-1600 RAM with 8-bit ECC
  • Flash — 8MB SPI NOR, plus 512MB SLC NAND
  • 2x SATA Gen 2 channels
  • SD/MMC controller
  • Video — 24-bit LCD controller; up to 1024×768 via LVDS output
  • Serial I/O — 6 TTL-serial; 2x I2C; 1x SPI
  • 2x USB 2.0 Host ports
  • Ethernet:
    • 2x 10/100/1000 autoselect ports
    • 2x 2.5G-capable ports
  • PCI Express bus — 1 x4 plus 2 x1 channels
  • 2x cryptographic and security acceleration engines
  • XOR/RAID – 4x high-speed XOR DMA engines for RAID storage apps
  • Power — 12V input @ 8W typ., 12W max., < 10mW sleep
  • Operating temp. — 0 to +70° C (standard)
  • Size — 70 x 75 mm

Mechanically, the CSB1726 conforms to Cogent’s unique “MXM SOM” (system-on-module) form-factor, which measures 70 x 75 mm and mates with low-cost, industry standard MXM-II sockets on application baseboards. Cogent’s MXM SOMs span multiple CPU architectures, including x86, PowerPC, MIPS, and ARM. Note: Cogent’s modules utilize the MXM II connector in a unique manner.

Cogent also supports the CSB1726 with a generic baseboard (shown below), to simplify the development of hardware and software in projects based on the module.
