Thermal management

The cooling system for the TQMLX2160A should be designed to dissipate a maximum of approximately 60 watts.
The power consumption of TQMLX2080A and TQMLX2120A are significantly lower.
The power dissipation originates primarily in the CPU the buck regulators and the DDR4 SDRAM.
The power dissipation also depends on the software used and can vary according to the application.
Attention: Destruction or malfunction, TQMLX2160A heat dissipation
The TQMLX2160A belongs to a performance category in which a cooling system is essential.
It is the user's sole responsibility to define a suitable heat sink (weight and mounting position)
depending on the specific mode of operation (e.g., dependence on clock frequency, stack height,
airflow, and software). Particularly the tolerance chain (PCB thickness, board warpage, BGA balls, BGA
package, thermal pad, heatsink) as well as the maximum pressure on the LX2160A must be taken into
consideration when connecting the heat sink.
The LX2160A is the highest component. Inadequate cooling connections can lead to overheating of
the TQMLX2160A and thus malfunction, deterioration or destruction.

Structural requirements

The TQMLX2160A should be fastened to the carrier board with spacer bolts or spacer sleeves at the four mounting holes.

Notes of treatment

To avoid damage caused by mechanical stress, the TQMLX2160A may only be extracted from the carrier board by using the
extraction tool MOZILX2160A that can also be obtained separately.
Note: Component placement on carrier board
2.5 mm should be kept free on the carrier board, on both long sides of the TQMLX2160A
for the extraction tool MOZILX2160A.

SOFTWARE

The TQMLX2160A is delivered with a preinstalled boot loader and a BSP, which is configured for the Starterkit carrier board
MBLX2160A. Documentation and more information about the BSP can be found in the
The boot loader provides TQMLX2160A-specific as well as board-specific settings, e.g.:
• CPU configuration
• DDR4 SDRAM configuration and timing
• eMMC configuration
• Multiplexing
• Clocks
• Pin configuration
• Driver strengths
