μQ7-A75-J

Whenever handling a μ

Q7-A75-J module, ground yourself through an anti-static wrist strap. Placement of the board on an anti-static

surface is also highly recommended.

1.4 Safety

The μQ7-A75-J 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-A75-J 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-A75-J 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.

μQ7-A75-J

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.

* Please consider that for HDD and Flash Disk manufacturers, 1GB = 10^9 Byte.

Some OS (like, for example, Windows) intends 1GB = 1024^3 byte, so global

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

management, so final capacity will be lower.

implement some (*) of the following extra functionalities:

- Additional SD interface

- Up to 4 UARTs

- CAN interface

Power Management Signals

Power supply voltage: +5VDC ± 5%

Optional Low Power RTC

Operating temperature: 0°C ÷ +60°C **

Dimensions: 40 x70 mm (1.57” x 2.76”)

** Temperatures indicated are the maximum temperature that the

heatspreader / heatsink can reach in any of its parts. This means that it is

customer

’

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

2.3 Electrical Specifications

According to Qseven® specifications, μQ7-A75-J 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 VCC power rail.

2.3.1 Power Consumption

TBM

2.3.2 Power Rails meanings

In all the tables contained in this manual, Power rails are named with the following meaning:

VCC: +5V voltage directly coming from the card edge connector

VCC_5V_SB: +5V stand-by external voltage

VCC_RTC: 3V coin cell voltage coming from the card edge connector for supplying the RTC clock on the i.MX6.

+3P3V_S: +3.3 switched voltage, derived internally.

μQ7-A75-J

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-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.

2.5 Supported Operating Systems

μQ7-A75-J 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.

3.2.1 Qseven® Connector

According to Qseven® specifications, all interface signals are reported on the card edge connector, which is a 230-pin Card Edge that can be inserted into

standard 230 pin MXM connectors, as described in Qseven® specifications.

Not all signals contemplated in Qseven® standard are implemented on MXM connector, due to the functionalities really implemented on μQ7-A75-J module.

Therefore, please refer to the following table for a list of effective signals reported on MXM connector.

Furthermore, many signals available on the card edge connector can be used to implement different functionalities, by exploiting the pin-muxing functionalities

offered by NXP i.MX6 processors.

For accurate signals description, please consult the following paragraphs. In the first instance, the signals with exclusive functionality will be described thoroughly.

After them, it will be given a table with a complete list of all pins with all possible alternative functionalities.

NOTE: Even pins are available on top side of CPU board; odd pins are available on bottom side of CPU board. Please refer to board photos.
