Q7-C25

1.4Safety

The Q7-C25 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 Q7-C25 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 Q7-C25 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.

Whenever handling a SM-B69 module, ground yourself through an anti-static wrist strap. Placement of the board on an anti-static

surface is also highly recommended.

Q7-C25

2.1Introduction

The Q7-C25 is a Q7 Rel. 2.1 compliant module with NXP i.MX 8M Applications Processors. Featuring multicore processing (Dual or Quad ARM Cortex®-A53 cores

+ general purpose Cortex®-M4 processor) and 4Kp60 HEVC decoding with HDR, it is a scalable solution designed by SECO for home automation, transportation,

digital signage and vending machines, and applicable to scenarios requiring advanced security, connectivity, multimedia and real-time response.

The module offers a very high level of integration, both for all most common used peripherals in the ARM domain and for bus interfaces typically used in the x86

domain, like PCI-Express.

Presented in the Q7 form factor, offering the computing abilities of a standard board, with the possibilities of combining with a ready-to-use carrier board like the

SECO CQ7-A42 or customised carrier board.

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 the integration of other peripherals/devices not already included in Q7-C25 module.

heatspreader temperature in the range indicated.

Please also check paragraph 4.1

Q7-C25

2.3Electrical Specifications

According to Qseven®specifications, Q7-C25 board 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_RUN power rail.

2.3.1 Power Consumption

Q7-C25 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 VCC power rail (5VDC)that supplies the board.

The power consumption has been measured in a Q7-C25 module with the following configuration on the commercial version:

-CPU iMX8M Quad 1.5GHz

-RAM DDR4 4GB, eMMC 8 GB

-LVDS + HDMI/DP video outputs

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.

2.3.2 Power Rails meanings

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

VCC: Power Supply +5VDC ±5%

VCC_5V_SB: Standby Power Supply +5VDC ±5%

VCC_RTC: 3V backup cell input. VCC_RTC is connected to a 3V backup cell for RTC operation and storage register non-volatility in the absence of system power

_RUN: Switched voltages, i.e. power rails that are active only when the board is in ACPI’s S0 (Working) state. Examples: +3.3V_RUN, +5V_RUN.

_ALW: 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_ALW, +3.3V_ALW.

Q7-C25

2.4Mechanical Specifications

According to Qseven®specifications, board dimensions are: 70 x 70 mm (2.76”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 itis also possible to use different connectorheights, also remainingcompliant

to the standard.

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

specifications, components placed on bottom side of Q7-C25 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.
