1.5 Tips on safety

Improper or incorrect handling of the product can substantially reduce its life span.

1.6 Symbols and typographic conventions

Table 1: Terms and Conventions

Symbol Meaning

This symbol represents the handling of electrostatic-sensitive modules and / or components. These

components are often damaged / destroyed by the transmission of a voltage higher than about 50 V.

A human body usually only experiences electrostatic discharges above approximately 3,000 V.

This symbol indicates the possible use of voltages higher than 24 V.

Please note the relevant statutory regulations in this regard.

Non-compliance with these regulations can lead to serious damage to your health and also cause

damage / destruction of the component.

This symbol indicates a possible source of danger. Acting against the procedure described can lead to

possible damage to your health and / or cause damage / destruction of the material used.

This symbol represents important details or aspects for working with TQ-products.

Command

A font with fixed-width is used to denote commands, file names, or menu items.

1.7 Handling and ESD tips

General handling of your TQ-products

The TQ-product may only be used and serviced by certified personnel who have taken note of the

information, the safety regulations in this document and all related rules and regulations.

A general rule is: do not touch the TQ-product during operation. This is especially important when

switching on, changing jumper settings or connecting other devices without ensuring beforehand

that the power supply of the system has been switched off.

Violation of this guideline may result in damage / destruction of the MBa65xx and be dangerous

to your health.

Improper handling of your TQ-product would render the guarantee invalid.

Proper ESD handling

The electronic components of your TQ-product are sensitive to electrostatic discharge (ESD).

Always wear antistatic clothing, use ESD-safe tools, packing materials etc., and operate your TQ-

product in an ESD-safe environment. Especially when you switch modules on, change jumper settings,

or connect other devices.

1.8 Naming of signals

A hash mark (#) at the end of the signal name indicates a low-active signal.

Example: RESET#

If a signal can switch between two functions and if this is noted in the name of the signal, the low-active function is marked with

a hash mark and shown at the end.

Example: C / D#

If a signal has multiple functions, the individual functions are separated by slashes when they are important for the wiring.

The identification of the individual functions follows the above conventions.

Example: WE2# / OE#

1.9 Further applicable documents / presumed knowledge

•Specifications and manual of the modules used:

These documents describe the service, functionality and special characteristics of the module used (incl. BIOS).

•Specifications of the components used:

The manufacturer’s specifications of the components used, for example CompactFlash cards, are to be taken note of.

They contain, if applicable, additional information that must be taken note of for safe and reliable operation.

These documents are stored at TQ-Systems GmbH.

•Chip errata:

It is the user’s responsibility to make sure all errata published by the manufacturer of each component are taken note of.

The manufacturer’s advice should be followed.

•Software behaviour:

No warranty can be given, nor responsibility taken for any unexpected software behaviour due to deficient components.

•General expertise:

Expertise in electrical engineering / computer engineering is required for the installation and the use of the device.

The following documents are required to fully comprehend the following contents:

•MBa65xx schematics

•TQMa65xx User’s Manual

•AM65xx Data Sheet

•AM65xx Reference Manual

•U-Boot documentation: www.denx.de/wiki/U-Boot/Documentation

•Yocto documentation: www.yoctoproject.org/docs/

•TQ-Support Wiki: Support-Wiki TQMa65Xx

2. BRIEF DESCRIPTION

This User's Manual describes the hardware of the MBa65xx as of revision 02xx. The MBa65xx is designed as a carrier board for the

TQ-Modules TQMa65xx.

Core of the MBa65xx is the TQMa65xx with a Texas Instruments AM65xx CPU.

The TQMa65xx connects all peripheral components. In addition to the standard communication interfaces such as USB, Ethernet,

etc., all other available signals of the TQMa65xx are routed on 100 mil standard pin headers on the MBa65xx.

CPU features and interfaces can be evaluated, software development for a TQMa65xx based project can start immediately.

Currently five Am65xx derivatives are supported:

•AM6526

•AM6527

•AM6528

•AM6546

•AM6548
