Timing of resetting EC21 module by RESET_N pin

IoT Modules LTE Standard Module

According to document EC21_Hardware_Desging, the EC21 module has some timing requirements to reset it by RESET_N pin.

Because we have a restriction on the precise timing in our microcontroller, it is not possible to keep the reset pulse between 150ms~460ms.

  • Can we hold the reset pin pulse for more than 1 second?

  • What happens to the module if the 460ms time for the reset pin is exceeded?

Thank you very much for your kind attention.

Exceeding this range will not cause any problems. But it cannot be less than 150ms.
