6.1.1 BoosterPack Plug-in Module: DLP-7970ABP

The third party provider DLP Design NFC/RFID BoosterPack™ plug-in module (DLP-7970ABP) is an add-on board designed to fit all of TI's MCU LaunchPad™ development kits. This BoosterPack plug-in module allows the software application developer to get familiar with the functionalities of TRF7970A multi-protocol fully integrated 13.56-MHz NFC/HF RFID IC on their TI embedded microcontroller platform of choice without having to worry about designing the RF section (see Figure 13 and Figure 14).

The TRF7970A device is an integrated analog front end and data-framing device for a 13.56-MHz NFC/HF RFID system. Built-in programming options make the device suitable for a wide range of applications for proximity and vicinity identification systems. The device can perform in one of three modes: reader/writer, peer-to-peer, or card emulation mode. Built-in user-configurable programming registers allows fine tuning of various reader parameters as needed.
