The RF430CL330HCPWR is a dynamic dual interface NFC Transponder is a NFC tag type 4 device that combines a wireless NFC interface and a wired SPI or I2C interface to connect the device to a host. The NDEF message in the SRAM can be written and read from the integrated SPI or I2C serial communication interface and can also be accessed and updated wirelessly through the integrated ISO14443B-compliant RF interface that supports up to 848kbps. This operation allows NFC connection handover for an alternative carrier like low energy (BLE) and Wi-Fi as an easy and intuitive pairing process or authentication process with only a tap. As a general NFC interface, the RF430CL330H enables end equipments to communicate with the fast-growing infrastructure of NFC-enabled smart phones, tablets and notebooks.
PI or I2C Interface to write and read NDEF messages to internal SRAM
Automatic checking of NDEF structure
