Whenever handling a μ
Q7-962 module, ground yourself through an anti-static wrist strap. Placement of the board on an anti-static
surface is also highly recommended.
1.4Safety
The μQ7-962 module uses only extremely-low voltages.
While handling the board, please use extreme caution to avoid any kind of risk or damages to electronic components.
1.5 Electrostatic Discharges
The μQ7-962 module, like any other electronic product, is an electrostatic sensitive device: high voltages caused by static electricity could damage some or all the
devices and/or components on-board.
1.6 RoHS compliance
The μQ7-962 module is designed using RoHS compliant components and is manufactured on a lead-free production line. It is therefore fully RoHS compliant.
Always switch the power off, and unplug the power supply unit, before handling the board and/or connecting cables or other boards.
Avoid using metallic components - like paper clips, screws and similar - near the board when connected to a power supply, to avoid
short circuits due to unwanted contacts with other board components.
If the board has become wet, never connect it to any external power supply unit or battery.
Check carefully that all cables are correctly connected and that they are not damaged.

2.1Introduction
μQ7-iMX6 is a CPU module, in μQseven®format, based on embedded NXP i.MX6 processor, an ARM®Cortex®-A9 processor, Single- Dual- and Quad-Core, with
frequencies up to 1.2GHz, which is ideal for applications requiring multimedia capabilities and/or high levels of parallel computing.
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 and S-ATA.
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 integrates three separated accelerators for 2D, OpenGL®ES2.0 3D and OpenVG , giving the processor incredible graphical
performances (OpenVG accelerator is not available with i.MX6 Solo and Dual Lite processors).
The board is completed with up to 2GB DDR3 (up to 1GB with i.MX6 Solo) directly soldered on board, and one eMMC Flash Disk, directly accessible like any
standard Hard Disk, with up to 32GB of capacity.
The board can support up to three 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. Please
be aware that using i.MX6 Solo and i.MX6 Dual Lite processors, only two independent displays at a time are supported.
HW video decoding of the most common coding standard (i.e., H.264, MPEG2, MPEG4, DivX, RealVideo and other) 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 , SATA, 2 x PWM Channels, Audio, one USB OTG port.
USB Hi-Speed interface drives an SMSC USB2514 USB2.0 Hi-Speed USB Hub Controller, which allows the board to have 4 USB 2.0 Host Ports.
RGMII i.MX6 native interface is internally carried to a Micrel KSZ9031RN Ethernet Transceiver, allowing the implementation of a Gigabit Ethernet interface
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-iMX6CPU module.

capacity shown for Disk Properties will be less than expected. Please also consider
that a portion of disk capacity will be used by internal Flash Controller for Disk

’
s responsibility to use any passive cooling solution along with an
application-dependent cooling system, capable to ensure that the
heatspreader / heatsink temperature remains in the range above indicated.
Please also check paragraph 4.1

2.3Electrical Specifications
According to Qseven®specifications, μQ7-962 module needs to be supplied only with an external +5VDC power supply.
5 Volts standby voltage needs to be supplied for working in ATX mode.
For Real Time Clock working and CMOS memory data retention, it is also needed a backup battery voltage. All these voltages are supplied directly through card
edge fingers (see connector’s pinout).
All remaining voltages needed for board’s working are generated internally from +5V_S power rail.
2.3.1 Power Consumption
μQ7-962 module, like all Qseven®modules, needs a carrier board for its normal working. All connections with the external world come through this carrier board,
which provide also the required voltage to the board, deriving it from its power supply source.
Anyway, it has been possible to measure power consumption directly on +5V_S power rail that supplies the board.
Module configuration
Average Power
consumption
i.MX6Quad @ 1GHz, 2GB LDDR3 memory, 8GB eMMC Disk
<5W
i.MX6Dual
TBM
i.MX6DualLite @ 1GHz, 1GB LDDR3 memory, 4GB eMMC Disk
<3W
i.MX6Solo Automotive @ 800MHz, 512MB LDDR3 memory, 4GB eMMC Disk
<2W
Please consider that power consumption is strongly dependent on the board’s configuration, on number of processor cores active and from the interfaces that are
SW enabled. PCI-express and SATA interface are particularly significant for power consumption, so it is strongly recommended to disable them (via SW) if they are
not used.
2.3.2 Power Rails meanings
In all the tables contained in this manual, Power rails are named with the following meaning:
_S: Switched voltages, i.e. power rails that are active only when the board is in ACPI’s S0 (Working) state. Examples: +3.3V_S, +5V_S.
_A: Always-on voltages, i.e. power rails that are active both in ACPI’s S0 (Working), S3 (Standby) and S5 (Soft Off) state. Examples: +5V_A, +3.3V_A.
Other suffixes are used for application specific power rails, which are usually derived from same value of voltage, switched rails (for example, +3.3V_CAM is
derived from +3.3V_S, and so on).

2.4 Mechanical Specifications
According to Qseven®specifications, board dimensions are: 40 x 70 mm (1.57”x 2.76”).
Printed circuit of the board is made of twelve layers, some of them are ground planes, for
disturbance rejection.
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 μQ7-962 will have a maximum height
of 2.2mm ± 0.1. Keep this value in mind when choosing the MXM connector’s height, if it is
needed to place components on the carrier board in the zone below the Qseven®module.
2.5 Supported Operating Systems
μQ7-iMX6 module supports the following operating systems:
Linux
Android
SECO will offer the BSP (Board Support Package) for these O.Ss, to reduce at minimum SW development of the board, supplying all the drivers and libraries
needed for use both with the Qseven®board and the Carrier Board, assuming that the Carrier Board is designed following SECO Qseven Design Guide, with the
same IC’s.
