I'm looking at the example PCB in tidrjd7 and the stack-up description in tirjd6. The impedance calculation for the antenna feed stripline from L2 doesn't yield 50ohm given the 30mil traces. The trace impedance calculates to about 95ohms. I must…
Part Number: TRF7970A Other Parts Discussed in Thread: TRF7963A , TRF7964A Hi,
Does TI have lower price solution for replace TRF7970A this kind of RFID/NFC Transceiver IC?
I've check TI website seems this series TRF7963A 1ku price ~ $1.7k.
Does there…
Part Number: TRF7970A Looking at the NFC Transceiver Reference Design: https://www.ti.com/tool/TIDM-NFC-TRANSCEIVER
The inductors in the matching circuit at the output of the IC use unshielded inductors.
Is there a requirement to use shielding between the…

Other Parts Discussed in Thread: TRF7970A , MSP-EXP430F5529LP , DLP-7970ABP , UNIFLASH Hello all,
I am currently looking at the TRF7970A NFC Transceiver for an NFC Reader/Writer application I am creating. I would like to purchase one of the recommended LaunchPad…
Part Number: TRF7970A I am having problems integrating a TRF7970A NFC Transceiver.
We built a mobile platform based on NXP's iMX8-Mini, and are running Yocto Linux Dunfell. The linux kernel has a driver for the TRF7970A, which I compiled and loaded ok…
Hi Chase,
the TRF7962A is not preferred for new designs, we recommend using the TRF7964A. It is based on a newer silicon version and offers a FIFO size of 127 bytes instead of 12 bytes.
TI offers a few reference designs including PCB data for the TRF79xxA…
