2.1 Introduction

μQ7-A75-J is a CPU module, in μQseven® format, based on embedded NXP i.MX 6Solo and 6Dual Lite, ARM® Cortex®-A9 processors, Single- or Dual-Core,

with frequencies up to 1GHz, which are ideal for applications requiring multimedia capabilities.

The board offers a very high level of integration, both for all most common used peripherals in ARM world and for bus interfaces normally used in x86 world, like

PCI-Express.

All this comes out in the extremely reduced space offered by μQseven® boards, which offers all functionalities of standard boards in just 40 x 70mm.

This solution allows combining the advantages of a standard, ready-to-use board, like μQseven® boards are, with all advantages offered by ARM application

specific processors like NXP i.MX6 processor, in its different versions (Single Core, Dual Core, Quad Core)

Moreover, NXP i.MX6 processors integrate three separated accelerators for Video Processing, Image Processing, 2D and 3D GPUs, giving the processor

incredible graphical performances.

The board is completed with up to 1GB DDR3L directly soldered on board (up to 512MB with i.MX 6Solo), and one eMMC Flash Drive, directly accessible like any

standard Hard Disk Drive, with up to 8GB of capacity.

The board can support two independent displays using dedicated video interfaces of the module: the first one, is a 24 bit Single/Dual Channel LVDS interface,

which can be configured to work as two independent 24 bit Single Channel interfaces. The other display interface is i.MX6’s native HDMI interface.

HW video decoding of the most common coding standard (i.e., H.264, MPEG2, MPEG4, DivX, RealVideo and other) is supported. Also MPEG-4, H.263 and

H.264 encoding is supported.

Many other features available through the standard Qseven® connector are native for i.MX6 processor: CAN Interface, UART interfaces, 1 x SD/SDIO/MMC

interface, PCI-express x1, 2 x PWM Channels, Audio, one USB OTG port, one USB 2.0 host Port.

RMII i.MX6 native interface is internally carried to a Micrel KSZ8091RN Ethernet Transceiver, allowing the implementation of a FastEthernet interface

The μQ7-A75-J module is part of SECO’s “Just! Embedded” product line, which are modules totally designed around the features offered by the SOC only, with

very few add-ons. This lead to essential, “ready-to-use” and “ready-to-market” products, which allow the reduction of design risks with minimal effort and cost. This

allows also to take the most advantage possible from the pin-multiplexing possibilities offered by the i.MX6 processors; indeed, most of the Qseven® standard

interfaces, when are not required, can be reprogrammed to offer other functionalities already implemented inside the i.MX6 processor itself.

Optionally, the module can be equipped with a low-power additional RTC, which would replace in working the i.MX6 native RTC (more power consuming).

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 μQ7-A75-J CPU module.

The MXM connector accommodates various connector heights for different carrier board

applications needs. Qseven® specification suggests two connector heights, 7.8mm and

7.5mm, but it is also possible to use different connector heights, also remaining compliant

to the standard.

When using different connector heights, please consider that, according to Qseven®

specifications, components placed on bottom side of μQ7-A75-J will have a maximum

height of 2.2mm ± 0.1. Keep this value in mind when choosing the MXM connector’s

height, if there is the need to place components on the carrier board in the zone below the

Qseven® module.
