Qseven/COM Express Compact modules with new Intel Atom

October 26, 2016 // By Graham Prophet
congatec has released COM Express Compact and Qseven Computer-on-Modules in time with the launch of Intel’s new low-power processors (code name Apollo Lake).

The modules with Intel Atom, Celeron and Pentium processors feature the powerful Intel Gen 9 graphics and deliver a performance-per-watt improvement, enabling the implementation of more powerful designs with lower energy consumption. This, combined with long-term availability of 10 years, offers both entry level COM Express Compact designs and high-end Qseven platforms.


Both form factors will support real-time applications. Those applications will benefit from the hardware integrated IEEE 1588 compliant Precision Time Protocol that can deliver nanosecond synchronization accuracy. Alternative software implementations need microseconds. There is also a hardware integrated audio DSP that can be used for new applications with speech recognition. Another convenient feature is the ability to switch from a static, hardware-based PCIe lane configuration to a flexible software-based setup which makes it possible to use the predefined GbE lanes of the modules also for other purposes.


The real-time capable congatec Qseven and COM Express Compact modules come with energy-saving Intel Atom processors E3930, E3940 and E3950 for the industrial-grade extended temperature range of -40°C to +85°C, or are fitted with the more powerful low-power dual-core Intel Celeron N3350 and quad-core Intel Pentium N4200 processors. Industrial-grade module variants with Intel Atom processors have a lidded cooling interface which connects directly to the processor. Therefore, no additional copper heat stack is required for most simple implementations and heat dissipation.


Hosting up to 8 GByte low-voltage DDR3 RAM onboard, the conga-QA5 supports 4k on up to three displays which can be controlled via dual channel LVDS, eDP, DP 1.2 and/or HDMI 1.4. For IoT connectivity and generic extensions, there are 1x Gigabit Ethernet interface, 4 PCIe lanes and 6 USB ports, one of which is provided as USB 3.0. Additional peripherals can be connected via 1x SPI and 1x serial interface. Two MIPI CSI camera inputs are further provided. For the integration of storage media, up to 64 GB of flash memory with fast eMMC 5.5, or
