1.3 Description
The Texas Instruments Dynamic NFC Interface Transponder RF430CL330H is an NFC Tag Type 4 device
that combines a wireless NFC interface and a wired SPI or I
2
C interface to connect the device to a host.
The NDEF message in the SRAM can be written and read from the integrated SPI or I
2
C serial
communication interface and can also be accessed and updated wirelessly through the integrated
ISO14443B-compliant RF interface that supports up to 848 kbps.
This operation allows NFC connection handover for an alternative carrier like Bluetooth, Bluetooth 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.
