Dear Kristi -
these designs were created with about the same intent as I think you have and they should give you some ideas. Here the point I am attempting to share with you is that the FRAM MCU can be partitioned and then leveraged for the logging, in…
Hello Helfried, my idea was get the energy for the TRF7970A from the field. Like in the TIDA-00721 use diodes to rectify the voltage and supply the VCC with it: http://www.ti.com/tool/TIDA-00721
The webpage and the datasheet mentioned that the TRF7970A…
Hello,
yes, the RF430CL330H can be used as passive tag for ISO14443B.
Because it requires an external microcontroller the reader has to provide enough power which is not always the case. The TRF7970A is well suited for a battery-less system.
Please see…
Dear Lin -
the application example for this with the LMT70, to do that application use case is here:

there is also the TMP116 and TMP117 which have been used in the…
Hi Ralph,
Thank you for the information - it is much appreciated.
So, can you please just confirm my understanding is correct? Basically, we could take the TIDA-00721 design and replace the NFC interface using the CC1101 (or similar) UHF design?

Hi Vijayan,
Below are some resources to consider for this design that use our existing sensors coupled with other devices to be read over air via NFC or BLE.

Hello Le,
That would come down to how much processing speed you need to keep up with the ADC. The CPU can run at up to 2 MHz, and the I2C bus at 400 kHz.
Depending your system requirements though, you may be better off doing something like this: http:…
Hi Feng bin Su,
TI does not have any non contact/(IR) temperature sensors. We do however have the LMP93601 that can be used with IR Array temperature sensors.
However, we do have other sensors that can be coupled with other devices to be able to be read…
Part Number: RF430CL330H Other Parts Discussed in Thread: TIDA-00721 , Hello All;
I have RF430CL330H (TIDA-00721 tag sensor), I can detect the tag by using external reader but when I tried with phone it doesn't detect at all!
The phone is HTC one M7…
Hello Ralph,
I want to use an NFC-enabled smartphone to get data from the tag via NDEF like in TIDA-00721. That's why I am looking for the sample code to program the RF430FRL152H.
Sincerely,
Binh
