NFC Key Features and Application from Silicon Craft Technology
228-Byte NFC Tag Type 2 with Built-in Sensor Interface
is a 228-byte ISO14443A passive NFC-Forum Type 2 Tag, which has the capability to connect with many kinds of analog sensors. With 12-bit-output-sigma-delta ADC (10-bit ENOB), SIC4340 can acquire the sensor’s voltage response at a specifc time after biasing by the adjustable current source,the adjustable sensor-biasing frequency generator and the voltage limiter.
The sensor can be either resistive, capacitive or combination of them. By relying on the computing power given in mobile devices and NFC communication, the SIC4340 becomes the mediator oﬀering the cheapest method conveying sensing information to display in mobile phone or even relay to internet.
