SAFETY REQUIREMENTS AND PROTECTIVE REGULATIONS
7.1
EMC
Since the MBLS1012AL is a development platform, no EMC tests have been performed.
7.2
ESD
Protection against electrostatic discharge is provided on most interfaces of the MBLS1012AL.
The circuit diagram shows which interfaces have ESD protection.
7.3
Operational safety and personal security
Tests for operational safety and personal protection were not carried out due to the voltages ≤30 V DC.
8.
CLIMATIC AND OPERATIONAL CONDITIONS
In general reliable operation is given when the following conditions are met:

Attention: Cooling
The LS1012A CPU belongs to a performance category in which a cooling system is essential in most
applications. 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 i.MX6UL must be taken into consideration when
connecting the heat sink. The i.MX6UL is not necessarily the highest component.
Inadequate cooling connections can lead to overheating of the TQMLS1012AL and thus malfunction,
deterioration or destruction.
8.1
Protection against external effects
Protection class IP00 was defined for the MBLS1012AL.
There is no protection against foreign objects, touch or humidity.
8.2
Reliability and service life
No detailed MTBF calculation has been done for the MBLS1012AL.
The MBLS1012AL is designed to be insensitive to vibration and impact.
