Consortium Releases Qseven Specification for Embedded Computer Module

The Qseven consortium has officially released and published version 1.0 of the Qseven specification. This now provides the ability for manufacturers of embedded computer modules to start their Qseven designs. Qseven is unlike previous Computer-On-Modules (COM) standards due to its primary focus being directed towards mobile and ultra mobile applications. It defines fast serial differential interfaces such as PCI Express and Serial ATA but omits support for legacy interfaces like EIDE and PCI in order to provide ideal support for today as well as future CPU’s and chipsets.

Qseven is the first COM standard that defines an integrative software interface. This Application Programming Interface (API) covers these important embedded features: Watchdog Timer, I²C Bus, LCD brightness control, BIOS user memory and system temperature. Qseven[tm] modules from different manufacturers can thus be easily exchanged without modifications to hardware or software.

The SDIO interface is also a new COM feature. Rugged and cheap SD-Cards can be used as bulk memory. Qseven defines an 8 Bit SDIO interface that is capable of supporting MMC 4.0 cards thereby providing a maximum data transition rate of 52 MByte/s. The Secure Digital Standard also enables other applications such as WLAN, Bluetooth, RFID, etc. while using the same card format.

In total, the Qseven standard features a rich choice of interfaces:

  • 4x PCI Express x1 Lanes
  • 2x SATA
  • 8x USB 2.0
  • 1000BaseT Ethernet
  • SDIO 8 Bit
  • LVDS 2x 24 Bit
  • SDVO / HDMI / DisplayPort (shared)
  • HDA (High Definition Audio)
  • I²C Bus
  • LPC (Low Pin Count Bus)
  • Fan Control
  • Battery Management
  • 5V Power (TDP max. 12 Watt)
  • Application Programming Interface (API)

The Qseven standard has been developed to utilize the latest low power technology in a small footprint form factor. Additionally, it defines battery management and a maximum power consumption of 12 Watts in order to enable mobile applications.

Today the consortium already includes 14 members:

  • congatec AG
  • MSC Vertriebs GmbH
  • Seco s.r.l
  • ASEM S.p.A
  • DAVE Srl
  • Grossenbacher Systeme AG
  • Hectronik AB
  • IEI
  • Portwell, Inc.
  • Tranquilpc Ltd.
  • Contradata
  • Elektrosil GmbH
  • HSM Zamecki
  • Matrix Electronica

The specification is freely available and may be used without any license fees. Membership in the QSeven consortium is also free of charge.
