Query on Internal protection diode in iMX8 processors

Avinash_h — Thu, 11 Mar 2021 07:30:09 GMT

Hello NXP team,

Can you suggest if iMX8 Dual X plus processor (IMX8DX5A) have internal protection or clamping diodes (for ESD protection) or not on its GPIO pins .

Thanks in advance,

Avinash

Hi Avinash

yes there are clamping diodes on gpio pins.

Hello igor,

Thank you for confirming.

Can you please share injection current specifications for the clamping diodes on these GPIO pins.

Thanks,

Avinash

Hi Avinash

sorry such injection current is not specified.

Hello Igor,

Thank you again for quick inputs.

Meanwhile is it possible to get those current details by any chance?

Because we need to judge do we need to use external clamping diodes or not.

Thanks,

Avinash

Hi Avinash

no chances, as these parametrs was not characterized (not measured on factory) so

nowhere to get it from.
