Choose the right part for my application

Other Parts Discussed in Thread: RF430CL330H, TIDA-00217

For an applicationi need to communicate between two devices.The stand-alone device is a low power device. I need a chip for this application that can get energy from a Radio Frequency (RF) (form the some board connected laptops  RF chip) so i can read-out data and write via RF data down on this chip (to the EEPROM). Also i need to write via (i2c) data in the EEPROM (or other non-violate memory). I found the RF430CL330H NFC Dynamic Tag Target Board, but so far i know it is only possible to read data from this chip via RF and not write data down to the memory via RF.

Is it possible and can you help me to select the possible chips, or give me advice for this problem? (Or when it’s not possible the most suitable chip combination)

Thanks

Mathijs

    Hello Mathijs,

    If you don't need EEPROM specifically and just need non-volatile memory, then you can pair the RF430CL330H device with an FRAM MSP430. You can store data that needs to be kept in non-volatile memory in FRAM.

    See this TI Design as an example: www.ti.com/tool/TIDA-00217

    The RF430CL330H needs to be controlled by an MCU regardless, and it only has SRAM, so the only way to use it and have non-volatile storage is to pair it with an MCU that can offer that storage.

    The only device we have that kind of has non-volatile memory built in is the RF430FRL15xH family. This our NFC sensor tag. However, it only has 2kB FRAM for application code+data storage so you'd be very size limited.

    Tanks for the response,

    the tida-00217 is a good example for me!
