Qseven module using the Intel Atom processor

Munich, Germany – The Qseven platform was specially developed with an eye on the latest low power processor technology and demand for small physical size. With a typical power consumption of < 5="" watts,="" mechanical="" dimensions="" which="" are="" scarcely="" bigger="" than="" a="" credit="" card,="" integrated="" battery="" management="" and="" acpi="" 3.0="" power="" management="" functions,="" the="" conga-qa="" is="" suited="" for="" all="" mobile="" applications.="" qseven="" is="" the="" first="" embedded="" module="" definition="" which="" defines="" a="" unique="" software="" interface.="" this="" api="" (application="" programming="" interface)="" covers="" functions="" which="" are="" important="" to="" many="" professional="" applications="" such="" as="" watchdog="" timer,="" ic="" bus,="" lcd="" brightness="" control,="" bios="" user="" storage="" areas="" or="" monitoring="" system="" temperatures.="" qseven="" modules="" from="" different="" manufacturers="" can="" therefore="" be="" exchanged="" flexibly="" without="" any="" hardware="" or="" software="" modifications.="">

The conga-QA module is suited for mobile applications

The new module provides fast, serial differential interfaces such as PCI Express and SATA, although it consistently avoids old “legacy” interfaces such as EIDE and PCI to ensure that future generations of CPUs and chipsets can also be used. It provides 8 x USB 2.0, 1 x SATA, 1 x SDIO, 1 x PCIe, LPC bus, IC bus as well as gigabit Ethernet and high definition audio. The module further offers up to 4 GByte onboard flash storage as an option for robust mass storage. The flexible SDIO interface means that SD cards can also be used as easy and robust mass storage. Thanks to the 8 bit bandwidth, MMC 4.0 cards can be used with a data transfer rate of up to 52 MByte/s. As well as storage media, cards with functions such as WLAN, Bluetooth, RFID, etc. are also available for the SDIO standard.

The conga-QA is available in two CPU variants. The cheaper version is based on the Intel Atom Z510 processor with 1.1GHz core frequency and 400MHz front-side and memory bus. In contrast, the high end version contains a 1.6 GHz Intel Atom Z530 (with 533MHz front-side and memory bus). Both versions have a 512k L2 cache and can access 512MByte on-board DDR2 storage.

The Intel US15W system controller hub contains the Intel GMA500 graphics engine. The 3D-capable on-board graphics use a frame buffer of up to 256MByte and support DirectX 9.0E and OpenGL 2.0. Video applications are accelerated by MPEG2 and MPEG4 decoding in hardware. Graphics output is either via a 1×24 bit LVDS channel or an SDVO port. The conga-QA module uses VESA standard “DisplayID” to automatically recognise any flat displays connected.

All congatec boards are equipped with the congatec embedded BIOS. They also contain a board controller, which implements some of the embedded BIOS expansions. The independence from the x86 processor means functions such as system monitoring or the IC bus are faster and more reliable, even when the system is in standby mode.
