https://community.nxp.com/t5/NFC/Request-for-Technical-Support-and-Documentation-for-NCx3321/m-p/2368084#M14227 <P>Dear Team,<BR /><BR />I am currently working on an application based on the NCx3321 device interfaced with a Texas Instruments MSPM0G3519 controller for authentication-related functionality. I would like to request your guidance and technical support regarding the integration process.<BR /><BR />Specifically, I am looking for:<BR /><BR />-NCx3321 datasheet and technical documentation SPI communication protocol details -Register map and initialization sequence RF field enable procedure<BR />-Reference software/examples or application notes<BR /><BR />Recommended development flow for card detection and authentication It would be very helpful if you could guide me on the recommended process and resources required to start development with the NCx3321 device.<BR /><BR />Please also let me know if there are any NDA requirements, SDK packages, or additional support channels that need to be followed for accessing the complete documentation. Looking forward to your support and guidance.</P> Wed, 20 May 2026 05:38:43 GMT Ja10 2026-05-20T05:38:43Z https://community.nxp.com/t5/NFC/Request-for-Technical-Support-and-Documentation-for-NCx3321/m-p/2368084#M14227 <P>Dear Team,<BR /><BR />I am currently working on an application based on the NCx3321 device interfaced with a Texas Instruments MSPM0G3519 controller for authentication-related functionality.
