Part Number: DLP-RF430BP Other Parts Discussed in Thread: RF430FRL152H , RF430CL330H , MSP430G2553 , TIDA-00217 , Dear Sir,
I am interfacing the dynamic NFC transponder RF430CL330H using evaluation kit NFCT4BTVALUE. I am new developer in NFC implementation.…
Hello Ahsan,
It is definitely possible to power a tag via the RF field from a reader device, and it's hardly as complicated as you laid out.
Given you have an on-body sensor, you may want to look at our RF430FRL152H which has a low-voltage (0.9V)…
Hello Ren,
I have used the Driver functions from the TIDA 00217 example. Temp_I2C_Init() and Temp_Read() are the two functions which are used. I call the Temp_Read() in main(). But I get stuck in
void Temp_I2C_Init ( void ){
//configure eUSCI for I2C
UCB0CTL1…
Hello Duncan,
I think we may have found the source of your problem. VDD2X can only source about 150uA when the device is in low power mode and that source is even lower when the device is running. I think your sensor is a bit too power hungry for it.…
Hello Fares,
It is possible to power an RF430CL330H and MSP430FR5739 with just the energy from the RF field of an NFC enabled smartphone. We have a TI Design demonstrating this but using the FR5969 instead of the FR5739: www.ti.com/.../tida-00217
Are you…
Hello Jeffferey,
The TI Design you linked is for the RF430FRL152H. The TI Design for a battery-less RF430CL330H tag is this one: http://www.ti.com/tool/TIDA-00217
For your questions:
Yes, this is possible. The RF430CL330H will need to be controlled by…
Hi Stella,
We do something similar with the TIDA-00217 design. It takes temperature data every 4 seconds and then updates an NDEF text record. We then reset the RF430CL330H so that the phone reads the new record. Have a look at the temp sensor example code…
Hello Paul,
Welcome to E2E!
Recommended Operating Conditions outline the voltage levels at which TI guarantees devices to properly function. Outside of this range, the device would be considered to operate out of spec and any behavior not matching the…
