General Description

The TI Dynamic NFC/RFID Interface Transponder RF430CL331H is an NFC Tag Type 4 device that combines a contactless NFC/RFID interface and a wired I2C interface to connect the device to a host.

The NDEF message can be written and read from the integrated I2C serial communication interface and can also be accessed and updated over a contactless interface using the integrated ISO/IEC 14443 Type B compliant RF interface that supports up to 848 kbps.

The device requests responses to NFC Type 4 commands on demand from the host controller and stores only a portion of the NDEF message in its buffer at any one time.
