    Hi Kelly,

    Thanks for reaching out.

    Yes, ISO1540 support clock stretching as the device has a bidirectional clock channel as well. This helps the MCU read clock channel back and allow clock stretching. While ISO1541 has unidirectional clock channel and hence doesn't support it. In summary, ISO1540 supports clock stretching. Thanks.
