ST25R3911B NRE IRQ firing - Errata document

[gentilkiwi]

Hello,

I'm experiencing somme issues on the ST25R3911B with the TIM/NRE IRQ firing, even after the end of receive (but without the nrt_emv flag).

> Basically the nrt_on flag is on even after receive, and I'm forced to send a CLEAR_FIFO/ STOP to stop this timer instead of having it stopped automatically.

I saw some errata references in the RFAL source code, but I don't find the errata documentation on the component webpage. Maybe I missed something, or can you please help me to find it? - https://www.st.com/en/nfc/st25r3911b.html#documentation

Bonus part: if you have the documentation and errata for ST25R3911 (not B) too, I will be interested.

Thank you in advance for your help :)

Hi,

This document related to ST25R3911B is not publicly available. Contact your local ST sales and marketing department to obtain this document.

As far as I know, the ST25R3911 (not B) is not part of the ST portfolio. Do you mean ST25R3912 or ST25R3914?

Hi Brian,

Thank you for quick answer.

I'm a little bit lost: both ST25R3916 and ST25R3916B have public erratas, but not ST25R3911B ? What are terrible secrets inside ?

As I'm an individual I don't have a local ST sales and marketing department, and I don't understand the idea to hide to others developpers this kind of information?

No, I mean ST25R3911 - The RFAL source code hase some errata references for 3911, and others for 3911B - it was on ST portfolio: https://web.archive.org/web/20180427204240/http://www.st.com/en/nfc/st25r3911.html
