Dear all,,,

Our application is using CYBT-343026-01 among Cypress BT modules.

The main module and Cypress BT module are connected in the form of a card cable,

and the function test has already been completed.

We are now conducting an ESD test at the system level, one of the reliability tests.

If 2kV is applied, the BLE module resets and ESD test fails.

When connecting the BT module to the main module of the system,

we need to advise for ESD protection and considerations for hardware design.

If you have an application note or any documents for that request, could you please provide us!

Thanks,

Best Regards,

PH

Table 26 in the datasheet recommends the maximum specification for ESD when the module is integrated into an

end system.

15KV over the air and 2KV for contact. Hope this helps.

Dear all,

We already know the ESD specification of the module you gave.

Now we are doing an ESD test at the system level, and if we apply ESD 2kV to the system,

the BT module resets and the ESD test failed.

In other words, if you have a hardware design guide to consider when using a BT module to pass an ESD test,

then we want to get help from Cypress.

Thanks,

Best Regards,

PH

You may need to deploy transient voltage suppression diodes (usually near to power supply inlets) in your end product so as to provide adequate protection against ESD.

Please open a technical support case or contact Cypress Korea for assistance.
