TIDA00524 problem with using RF430CL330H instead of RF430CL331H

Other Parts Discussed in Thread: RF430CL331H, RF430CL330H, TIDA-00524, MSP430FR5969, TIDA-00217

Hello everyone, 

I rebuild the model TIDA 00524 hardware for practicing. My model is exactly the same except I used RF430CL330H instead of RF430CL331H. The cold chain code provided by TI for TIDA00524 did not work on my model. I want to know if the change of RF430 type causes the problem. According to my understanding they should be similar. If this is the problem. Is there an easy hack to change TI code to work with my model or do I need to rewrite the whole code for RF430 to adapt.

Thank you for your help.

    Hello Alaaedden,

    There are major differences between the devices, so you will need to re-write the code significantly if you swapped devices. Furthermore, the CL331H was used for that application because it offers a way to send significantly more data over NFC. With the CL330H, you won't be able to send more than 3kB of data which also makes the storage system of holding 40+ kB of sensor data on the MSP430FR5969 mostly pointless. You will want to re-work that as well. Frankly, I don't see any reason for you to use the CL330H over the CL331H unless you have an application that is far different than the intent of the TIDA-00524 design.

    Section 2 of our device FAQ for the RF430CL33xH devices covers the differences between these two parts: http://www.ti.com/lit/pdf/sloa244

    The problem was in the schematic diagram. They mentioned CL330H instead of CL331H which made me confused. Anyway I ordered CL331H and replaced it in my designed PCB. It still didn't work for me. It is like the antenna is noticing my phone at all. I troubleshooted it for some time and I still can't put my hand on the main cause of the problem. I want to know if the ground plane might affect the antenna performance, as it is the only different thing I might have from TIDA 00524 design.

    Thanks a lot for your help

    Hello Alaaedden,

    That shouldn't be an issue for that kind of board. In general we like having more room between the ground plane and the antenna coil, but even on our TIDA-00217 board we had them fairly close and still get communication without much difficulty.

    Are you getting any traffic on the I2C lines?

    Thank you a lot ralph,
    I fix the problem, so after you told me the ground plane should not be the problem. I start troubleshooting it for couple of day, until I figure out that the problem was with short between the antenna's terminals .
    Thank you again for the help, I really appreciate it.
