1.5 Tips on safety
Improper or incorrect handling of the product can su stantially reduce its life span.
1.6 Sym ols and typographic conventions
Ta le 1: Terms and Conventions
Sym ol Meaning
This sym ol represents the handling of electrostatic-sensitive modules and / or components. These
components are often damaged / destroyed y the transmission of a voltage higher than a out 50 V.
A human ody usually only experiences electrostatic discharges a ove approximately 3,000 V.
This sym ol indicates the possi le 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 sym ol indicates a possi le source of danger. Acting against the procedure descri ed can lead to
possi le damage to your health and / or cause damage / destruction of the material used.
This sym ol represents important details or aspects for working with TQ-products.
Command A font with xed-width is used to denote commands, le names, or menu items.
1.7 Handling and ESD tips
General handling of your TQ-products
The TQ-product may only e used and serviced y certied 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 eforehand
that the power supply of the system has een switched o.
Violation of this guideline may result in damage / destruction of the MBLX2160A and e 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 MBLX2160A UM 0100 l © 2021, TQ-Systems Gm H 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 etween 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 y slashes when they are important for the wiring.
The identication of the individual functions follows the a ove conventions.
Example: WE2# / OE#

2 BRIEF DESCRIPTION
This User's Manual descri es the hardware of the MBLX2160A revisions 01xx and 02xx.
The MBLX2160A is designed as a carrier oard for the TQMLX2160A.
All TQMLX2160A interfaces, which can e used, are availa le on the MBLX2160A, thus the features of the LX2160A
can e evaluated and software development for a TQMLX2160A- ased project can e started directly.
The MBLX2160A supports TQMLX2160A modules with an LX2108A, LX2120A or LX2160A CPU.

User's Manual l MBLX2160A UM 0100 l © 2021, TQ-Systems Gm H Page 5
3 ELECTRONICS
The oot ehaviour of the TQMLX2160A can e customised. The required oot-mode conguration can e set with DIP switches
on the MBLX2160A, see chapter 3.1.3.
3.1 TQMLX2160A
The TQMLX2160A with its LX2160A CPU is the central system component. It provides DDR4 SDRAM, eMMC, NOR ash and an
EEPROM. All TQMLX2160A internal voltages are derived from the 5 V supply voltage. Further information can e found in the
TQMLX2160A User’s Manual. The availa le signals are routed to the MBLX2160A via three connectors. On the MBLX2160A the
interfaces provided y the TQMLX2160A are routed to industry standard connectors. Furthermore the MBLX2160A provides all
power supplies and congurations required for the operation of the TQMLX2160A. The MBLX2160A supports TQMLX2160A
modules with an LX2108A, LX2120A or LX2160A CPU.
Figure 2: Block diagram TQMLX2160A
The following functionalities and interfaces are provided y the MBLX2160A:
1 × QSFP28 slot for 100 G it Ethernet module
2 × SFP+ slots for 10 G it Ethernet modules
6 × 1 G it Ethernet
3 × SATA
3 × PCIe / 2 × mPCIe
2 × CAN
SD card
2 × USB 3.0 / 1 × USB OTG
Power supply and voltage supervision
Multiplexing conguration y DIP switches
OLED display for additional information

To avoid damaging the connectors of the MBLX2160A or the TQMLX2160A while removing the TQMLX2160A, the use of the
extraction tool MOZILX2160A is strongly recommended.
Note: 16 G it+ specication
It is strongly recommended to use 220-pin connectors on carrier oards that comply with the
16G it+ specication. For the 120-pin connectors the 10 G it+ specication is sucient.
3.1.2 TQMLX2160A pinout
All availa le TQMLX2160A signals are routed to three connectors on the MBLX2160A.
More detailed information is to e taken from the TQMLX2160A User’s Manual 4.
The direction of the signals in the following ta les are seen from the TQMLX2160A's perspective.
Note: Availa le interfaces
Depending on the TQMLX2160A derivative not all interfaces are availa le. Refer to the TQMLX2160A
User’s Manual and the TQMLX2160A pinout ta le to see which interfaces are availa le.
When using the processor signals, it is essential to pay attention to the multiple pin assignment y
dierent CPU functions (multiplexing).
The pin assignments shown in the following ta les refer to the MBLX2160A.

3.1.4 eMMC cong
The TQMLX2160A allows a varia le conguration of the SDHC2 interface via the control signals eMMC_SEL[1:0].
These signals are pulled-up to 3.3 V on the TQMLX2160A y default. Based on the eMMC_SEL[1:0] setting the MUX devices at
SDHC2 are switched accordingly. The eMMC_SEL[1:0] conguration cannot e changed during runtime!

3.1.5 NOR Flash swap
The TQMLX2160A allows an easy toggle of the two XSPI NOR Flash devices. Only the chip select of oth devices are swapped, so
that from the view of the CPU no dierences appear. This is controlled y the signal NOR_SWAP#. The signal has a pullup to 3.3V
on the TQMLX2160A. Alternatively a software conguration via I²C slave register is provided.
