RF430FRL152H: Something about Digital Sensor.

Part Number: RF430FRL152H

Hello,

        Assume that the reading rate of NFC reader is 200Hz and there is an external digital ADC(Sampling rate is ~200Hz) with I2C, and the digital ADC is low power consumption. Can I use rf430frl52h to realize NFC transmission of digital sensor data(200Hz)?

Best regards

    Hello Senhao,

    this is a tough goal. This means you will have to sample every 5ms. The I2C bus seems fast enough with 400kHz but you also have to consider to read the data fast enough from the memory. An ISO15693 "Read Single Block" with a 8 byte block size will take 5.6ms, with 4 byte block size 4.4ms. Because we never tried to work with speeds like that, we can not guarantee that this will work. This has to be evaluated by yourself.

    Best Regards,
