Introduction
Q7-974 is a CPU module, in Qseven
®
format, based on the Intel
®
Atom family of System-on-Chips (SOCs), formerly coded as Bay Trail, CPUs, a series of Single/
Dual / Quad SOCs with 64-bit instruction set.
These SOCs embed all the features usually obtained by combination of CPU + platform Controller hubs, all in one single IC, which allows, therefore, the system
minimisation and performance optimisation, which is essential for boards with sizes so reduced as for Qseven
®
boards, which offers all functionalities of standard
PC boards in just 70x70mm.
The board is also available in an EXTREME configuration, with all the components mounted onboard certified for industrial temperature ranges (this configuration is
not available with the Celeron
®
processors).
The embedded memory controller allows the integration of up to 8GB of DDR3L Memory directly soldered onboard, speed up to 1333MHz (it depends on the SoC
used).
All SOCs embed an Intel
®
HD Graphics 400 series controller, which offer high graphical performances, with support for Microsoft
®
DirectX11, OpenGL 3.0,
OpenCL 1.2, OpenGLES 2.0 and HW acceleration for video decoding of H.264, MPEG2, MVG, VC-1, VP8 and MJPEG video standards (for H.264, MPEG2 and
MVG also HW encoding is offered). This embedded GPU is able to drive two independent displays, by using the interfaces available on Qseven
®
golden finger
connector and/or the VGA dedicated connector.
Mass Storage capabilities of the board include up to two external S-ATA channels, a standard SD interface and one optional SATA Flash Disk soldered on board.
Other than the interfaces already discussed previously, on Qseven
®
golden finger connector there are the signals necessary for the implementation of Gigabit
Ethernet, one USB 3.0 port, up to 5 x USB 2.0 ports, 18/24-bit Single/Dual Channel LVDS or embedded Display Port interface, HDMI or multi-mode DisplayPort
interface, 3 x PCI-Express x 1 lanes, HD Audio interface, I
2
C, SPI, LPC and SM buses, UART interface.
Interfacing to the board comes through a single card edge connector, whose pinout is defined by Qseven
®
specifications Rel.2.0. For external interfacing to
standard devices, a carrier board with a 230-pin MXM connector is needed. This board will implement all the routing of the interface signals to external standard
connectors, as well as integration of other peripherals/devices not already included in Q7-974 CPU module.
Please refer to following chapter for a complete list of all peripherals integrated and characteristics.
