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 MBa57xx 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.

User's Manual l MBa57xx UM 0100 l © 2020, 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

2. BRIEF DESCRIPTION
This User's Manual describes the hardware of the MBa57xx Revision 02xx. The MBa57xx is designed as a carrier board for the
TQMa57xx. The illustrations in this User's Manual refer to the TQMa57xx. All interfaces provided by the TQMa57xx are available
on the MBa57xx. The function of the AM57xx can be evaluated, and therefore the software development for a TQMa57xx project
can start immediately. The MBa57xx supports all TQMa57xx modules with AM5718, AM5728, and AM5748 Single or Dual
Cortex®-A15 CPUs. More details may be taken from the AM57xx documentation, see Table 60.

3.1.2 Functionality
Core of the system is the TQMa57xx with a TI AM57xx CPU. In addition to the standard communication interfaces like USB,
Ethernet, RS-232, RS-485, etc. all other available signals of the TQMa57xx are routed to 100 mil standard headers.
The MBa57xx provides the following interfaces and functions:

The available signals are routed to four connectors on the MBa57xx.
Note: TQMa57xx interfaces
Depending on the selected TQMa57xx, not all interfaces are available.
Available interfaces are to be taken from the TQMa57xx User’s Manual
or the pinout tables in chapter 4.1.1.3.
The pin assignments listed in Table 4 to Table 7 refer to the BSP provided by TQ-Systems GmbH.

4.1.2 I2C address mapping
Illustration 3: Block diagram I2C buses on TQMa57xx and MBa57xx
The TQMa57xx offers two I2C interfaces, which are available on the TQMa57xx connectors as primary function.
I2C1 is a TQMa57xx internal I2C bus, which is exclusively used for the I2C devices on the TQMa57xx. This bus is not available.
The corresponding addresses can be taken from the User's Manual of the TQMa57xx (12).
I2C5 is routed to header X48 on the MBa57xx, no I2C devices are connected.
Further I2C interfaces can be provided by an adapted pin multiplexing.
The following table shows the signals used on the two I2C interfaces:
Table 8: I2C signals
Signal Direction MBa57xx Remark
I2C4_SDA I/O X1-88 2.7 kΩ PU to 3.3 V on MBa57xx
I2C4_SCL O X1-90 2.7 kΩ PU to 3.3 V on MBa57xx

I2C5_SCL O X1-96 2.7 kΩ PU to 3.3 V on MBa57xx
The following table shows the I2C4 addresses used on the MBa57xx.

4.1.3 Temperature sensor
The MBa57xx does not provide a temperature sensor. However, on the top side of the TQMa57xx is a temperature sensor
SE97BTP with integrated EEPROM.
4.1.4 RTC backup
The TQMa57xx provides a DS1339U-33 RTC, which is connected to the I2C1 bus.
To supply the RTC on the TQMa57xx, a 3V lithium battery type CR2032 with very low self-discharge is mounted on the MBa57xx.
The following tables show details of the RTC backup supply.
Table 10: RTC backup supply

User's Manual l MBa57xx UM 0100 l © 2020, TQ-Systems GmbH Page 14
4.1.5 Port Expander
Two PCA9555PW port expanders with 16 ports each are used to control several components on the MBa57xx. These include the
buzzer, user LEDs, user GPIOs, configuration signals for mPCIe and push buttons.
The port expanders are configured via I2C4. The expander addresses can be changed by rearranging resistors. When changing
the address, care must be taken to avoid address conflicts with existing I2C devices. The assembly options are documented in the
MBa57xx circuit diagram. In the initial state after power-on all ports are set as input.
