Part Number: TRF7970A
Other Parts Discussed in Thread: DLP-7970ABP, , RF430CL330H

Hi Team,
I am looking for an NFC module for the firmware update to one of our products. the chip TRF7970ARHBT seems a good option for me. Is there any module available for this chip so that I can directly place that muddle to my PCB and connect t the necessary connections like VCC, GND, and I/O to my controller?.

Hi Shibin,

there is a module available. It is the DLP-7970ABP a so called BoosterPack for our Launchpads:

hi HV,
Thank you for your reply.
This module seems very large to place on our carrier board.
What I'm looking for is a module of NFC alone like in the red circle below

with a provision to connect its power and I/O for communication with the MCU and the provision to connect to its loop antenna.
Do TI offers such solutions?.

Hi Shibin,

this is the only module TI offers for the TRF7970A. The purpose of this module is to give the customer a tool for evaluation and software development. For a final product it is up to the customer to develop its own solution.

To support own customer designs TI offers reference designs with all design data:

The DLP-7970ABP is what you want to have. It does not contain the MCU. Only when you want to connect your only antenna you have to make changes to the board.

Best Regards,

Helfried

Hi Shibin,

if you asking for any reader modules, no, there are no other NFC modules. The only other module is for the RF430CL330H transponder which can be used to communicate via NDEF message:
