The power-on time of any interface of the module should not be earlier than the power-on
time of the module, otherwise it may cause the module to be abnormal or damaged.
5.5 Static characteristics
The internal design of CLM920_RC3 module has been considered and corresponding ESD
protection has been considered, but ESD problems may also occur in the production
assembly and experimental testing of the module, so application developers need to consider
the ESD protection of the final product.
In addition to the recommended circuit of the interface design of the reference document, the
customer also needs to pay attention to the following points when designing:
The PCB layout of the protection device should try to follow the "V" line and avoid the "T"
line.
The ground plane around the module guarantees integrity and should not be split.
In the process of module production, assembly and laboratory testing, it is necessary to pay
attention to the surrounding environment and the ESD control of operators.
