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 MBa62xx 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.

Preliminary User's Manual l MBa62xx UM 0001 l © 2023, TQ-Systems GmbH Page 3
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.
•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:

2. BRIEF DESCRIPTION
The MBa62xx is designed as a carrier board for the TQMa62xx and TQMa62xxL All TQMa62xx interfaces are available on the
MBa62xx. The AM62x CPU characteristics can be evaluated, and therefore the software development for a TQMa62xx project can
be started immediately.
The MBa62xx supports all TQMa62xx as well as TQMa62xxL (via adapter TQMa62xxL-ADAP) modules. In the further course of this
User Manual, only the TQMa62xx module is mentioned for the sake of simplicity - however, all statements apply accordingly to
the TQMa62xxL module as well.
