Could you please let me know what kind of doubt you have? The red marked difference at the top is part of the device symbolization, which should be visible from the outside without x-ray. The difference can be explained by difference in lot and date code. I don&#39;t know what the marked difference in the middle is caused by. Maybe it is some contamination on the inductor for the not marked device. Is this consistent on all devices of that lot? The marked difference at the bottom of the image does not look different to me. What do you mean here? Best regards, Andreas.https://e2e.ti.com/support/wireless-connectivity/other-wireless-group/other-wireless/f/other-wireless-technologies-forum/1644583/cc2755p10-we-need-complete-datasheet-and-programming-specs-of-cc2755p207e0wrhar/6343257Wed, 13 May 2026 08:41:00 GMTcb01d8b2-d089-468d-babb-77d1d8683490:b8cd1ecd-0e1c-427c-bad8-31bbd1e9e41bSarthak ChatterjeeHi FI, Please provide an update on this, this is an HOT urgent request.

All of the certification is done on product system (or module clause) level. As a proved product, there had been plenty of customer’s product pass SRRC (or CE/FCC). so what&#39;s your support needs behind? BR.
