Hi,
This is what I will recommend you to do. Please refer to this app note. NFC/HF RFID reader/writer using the TRF7970A . This app note has the example project built for MSP430F5529 LaunchPad. Build the project and you shouldn't have issues with the…
Raphael,
Thanks for the additional data. I agree, that the power ramp looks okay without dips.
10mA @3V seems like a large amount of power to harvest from the NFC field unless the reader is fairly powerful. From my past testing, readers such as NFC…
Hello Aravind,
the TRF7970A and the TRF7964A would be suitable reader/writer ICs, which can be used for building NFC door locks with cards (see also this Technical Article: https://e2e.ti.com/blogs_/b/process/posts/nfc-rfid-for-access-control-sniffing…
Hello Jeff,
The recommended devices for new design-ins are the TRF7964A www.ti.com/product/TRF7964A and the TRF7970A www.ti.com/product/TRF7970A .
Both devices are pin-to-pin and SW compatible.
TRF7964A – supports multi-protocol reader/writer…

HI,
Madeleine McSwain said: Also, since the TRF7970AEVM is not available for purchase, I'm unsure what is the best method to communicate with the device. Do you have any suggestions if I cannot get the NFC Tools app to work
TRF7970AEVM is discontinued…
Isogai Takeshi said: The data to be written is the data in Table 1 in the UserData area (2048 bytes) of the memory map in the figure below.
could you let us know how to use TI NFC Tool Ver1.8 and write with Tag Write.?
I don't think the GUI…

Hi Team,
I am trying to modify several GPIO interfaces of the CC2642 to SPI interfaces to drive my SPI device (RC522 card reader). The SPI interface names and pin definitions I want to use are as follows:
// SPI Pin…
Hello Ernest,
are you referring to NFC on the reader side or on the tag side?
Reader IC's would be the TRF7970A and TRF7964A .
Readable and writable Tag devices can be found in our Tag-it portfolio or with the RF37S114 .
Tag devices with I2C interface…
Hi Brandon,
What is your sample rate? If the maximum number of rotations is exceeding the upper limit set by your sample rate it is possible that you could miss some counts. Does your flow rate vary in this setup or is it constant?
=> The same rate…
