1.6 Safety and Handling Precautions
DO NOT exceed the rated maximum values for the power
supply! This may result in severe permanent damage to
the unit, as well as possible serious injury.
ALWAYS keep the unit dry, clean and free of foreign
objects. Otherwise, irreparable damage may occur.
Parts of the unit may become hot during operation. Take
care not to touch any parts of the circuitry during
operation to avoid burns and operate the unit in a well-
ventilated location. Provide an appropriate cooling
solution as required.
ALWAYS take care of ESD-safe handling!
Many pins on the module connector are directly
connected to the CPU or other ESD sensitive devices.
Make or break ANY connections ONLY while the unit is
switched OFF.
Otherwise, permanent damage to the unit may occur,
which is not covered by warranty.
There is no separate SHIELD connection.
The module’s mounting holes are not connected to GND
Take this into account when handling and mounting the
unit.

3.3 Power Consumption
The MPX-LS1028A is supplied by a single input power rail of 5V nominal.
The typical power consumption values for the module are determined on a CRX07
carrier running U-Boot (idle) at room temperature with heatsink and 25mm fan:
■LS1028A (dual core)
■CPU core frequency 1500 MHz (2 cores enabled / 1 core used by U-Boot)
■400 MHz bus clock
■4 GBytes of DDR4 memory + ECC (1600 MHz)
■~5.6 Watt
3.4 Cooling
In chapter 3.3 the power consumption of the MPX-LS1028A module was specified.
With this information a cooling method needs to be designed suitable for the final
use case. If desired, MicroSys Electronics GmbH can support you with your cooling
concept. Please ask your sales representative or send an email inquiry to
support@microsys.de.
Please make sure that the cooling solution is always sufficiently dimensioned to
keep the operating temperature of all parts below the maximum specified
temperature.
The most critical parts are listed in the following tables.

4.1 Pinouts
The signal direction is from the module’s view. For example, DP_LANE3_P (pin B39)
is an output from the module and an input to peripheral devices on the carrier board.
The following table gives an overview of the 230 pins of the module’s edge finger.
For a detailed connector description see chapter 5.1. The pins will be described in
chapter 4.10 and the following sections.
The signal names in the following two tables do not show all available options for
each pin. Pin multiplexing can only be implemented in combination with the
vendor’s datasheet.

4.2 Power Structure
The MPX-LS1028A module is supplied by a single 5V supply. For RTC backup
buffering an additional supply from the carrier board is necessary.
The module itself does not provide any supply voltage to the carrier but it has some
reference voltages that show the voltage level of the respective interface on the
module. If necessary, the carrier board must track the reference voltages and
generate a copy which can carry higher loads.
The following diagram shows the structure of the power supplies:
The following table shows the internal connections:
