Qseven compute module hosts Quad-core Intel Pentium with 4K graphics

The conga-QA4 module from congatec offers lower power dissipation, provides more processing power and comes with the new integrated Intel Gen 8 graphics

The latest addition to congatec’s Qseven family, the conga-QA4 module hosts the new Intel Pentium and Celeron processors based on 14 nm technology and offers increased energy savings and computing power. The optimised Intel Gen8 graphics, with up to 16 EUs (graphics execution units) and 4K (3840 x 2160 pixels) resolution, result in a significantly improved visual experience.

The conga-QA4 module comes in three different processor versions (Intel codename Braswell) for high scalability. These range from the entry-level dual-core Intel Celeron N3050 with 1.6/2.08 GHz to the quad-core Intel Pentium N3700 with 1.6/2.4 GHz, each with a power consumption of 4W for standard applications (SDP = Scenario Design Power).

Qseven modules featuring the first Intel Atom processor generation have been in use since 2008. With the introduction of the new conga-QA4 module, all Qseven applications can now be upgraded to the latest processor technology quickly and easily.

The Qseven module is equipped with up to 8 GB dual channel DDR3L memory and up to 64 GB eMMC 5.0 for mass storage. The enhanced integrated Intel Gen8 graphics supports DirectX 11.1, OpenGL 4.2 and OpenCL 1.2. The new high-performance, hardware-accelerated video decoding of H.265/HEVC, requires a 50% lower data rate compared to H.264/AVC, making it possible to stream 4K videos in real time.

Up to 4K(3840 x 2160 pixels) resolution is supported by either DisplayPort or HDMI interfaces. In addition the conga-QA4 module has a default 24-bit LVDS interface. The Qseven specification includes an optional pinout which replaces the LVDS interface by two sets of Embedded DisplayPort signals. This optional implementation allows to operate three independent displays. There is a MIPI CSI 2 camera interface. Using a feature connector conforming to the Qseven SGET 2.0 specification (Addendum), the conga-QA4 module can directly support up to two MIPI HD cameras. The main advantage of MIPI-CSI2 lies in the low price of camera modules supporting the MIPI-CSI2 interface.
