Part Number: TRF7970A Hello,
When emulating a standard 14A tag with TRF7970A, all is ok with many devices (including phones & tablet)
But when testing with some devices (like Pixel 7A, Pixel 7 Pro), it seems that Android discovering routines includes…
Part Number: TRF7960A Other Parts Discussed in Thread: TRF7970A , TRF7960 Hi,
I am trying to initialize the Msp430F5529LP with TRF7970a. how can I initialize and read and write the data from TRF7970A to MSP430F5529LP board.
Part Number: TRF7970A I am working on an application for a TRF7970A based on sloc297 code.
Beside of reading specific Tag data I want to use the "findTag" result to detect the pysical presence of tagged parts in my device (to see if the mechanical slot…
Part Number: TRF7970A Dear champs,
I am asking this for our customer.
The user follows below to start up TRF7970A,
Then, use below for initialization.
Then, use host MCU SPI to read registers below. But it is weird that all of the registers are all…
Part Number: TRF7970A Hello,
I have a PCB that uses the TRF7970A for NFC detection that has been in production for 3 years. We have recently started observing cases where the rest of the board is fine, but the TRF no longer responds to the MCU. I have…
Adiitional investigation shows that, as soon as we send the last write in DM1 enter sequence (0x00 0x61, 0x00), RF goes off just like this other post:

Part Number: TRF7970A I am looking to test and compare the performance of the TRF7970A when operated in half and full power modes. According to the datasheet, the output impedance differs between half and full power (8Ω typ for half power and 4Ω typ for…
Part Number: TRF7970A Other Parts Discussed in Thread: MSP-EXP430F5529LP , Team,
my customer is using DLP-7970ABR + MSP-EXP430F5529LP for tests. They now want to design their own custom TRF7970A board.
What signals are needed to interface their custom board…
Part Number: TRF7970A What is the maximum antenna size (in terms of Inductance) I can use with TRF7970A?
Why TI is using 0.950 uH antenna in their design? Is there any specific reason behind this decision?
