PN7642 documentation

ArtemPN — Fri, 28 Jun 2024 13:51:33 GMT

Hello!

I`m using PN7642. I would like to read some documents containing IC`s peripheral detailed description and registers description. Also I would like to know if there are documents which describe bootloader communication protocol for FW programming via, for example, SPI interface.

Can someone suggest where to look for such information? May be somewhere more related documents are available for PN7642?

Thank you in advance!

Artem

Hello @ArtemPN

Hope you are doing well.

For more information about PN7642, you can consult the PN76 family instruction manual and UM11566 PN76 family NFC open controller user manual (since this document is under NDA, it is secured in Secure Files, and you will need to request access to it).

Regarding the firmware download, perhaps you may find useful the Secure Firmware Download example "DownloadLibEx1", which is available to demonstrate the secure firmware update by using LPC55 and MCUXpresso. You can find more information on this in PN76 family evaluation board quick start guide, Chapter 4 Software.

Regards,
Eduardo.

Thank you for reply. Now it is clear. I will try to sign NDA to be able to use this documentation.
