DLP-RF430CL331BP BoosterPack User’s Guide FEATURES: • • • • • • • • • Texas Instruments RF430CL331H ISO14443B Compliant 13.56MHz RF Interface Supports up to 848 Kbps NFC Tag Type 4 Compliant 3K SRAM Bytes Available for NDEF Message Storage Automatic Checking of NDEF Structure Interrupt to Indicate End of Read or End of Write Onboard Antenna or Optional External Antenna Connection (Remove R2 and R3) Operational Power Supplied by the LaunchPad (Purchased Separately) 1.0 INTRODUCTION The DLP Design DLP-RF430CL331BP BoosterPack is used to demonstrate the capabilities of the RF430CL331H and help aid in the development process by providing a working hardware/firmware reference example for NFC operations. This BoosterPack demonstrates a secure, simplified pairing process for Bluetooth® and Wi-Fi connections with the only dynamic NFC tag device designed specifically for NFC connection handover and service-interface functions. The main benefit of the DLP-RF430CL331BP vs. DLP-RF430CL330BP is that you can now use the device in a “pass-through” mode where the connected microcontroller (LaunchPad) handles the commands which are sent by the reader/writer device. This allows for NDEF messages larger than the 3KB limit of the CL330H. The only limitation is the size of the memory in the microcontroller. The RF430CL331H 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. This allows NDEF message size to be limited only by the memory capacity of the host controller and specification limitations. Support of read caching, prefetching, and write automatic acknowledgment features allows for greater data throughput. The DLP-RF430CL331BP BoosterPack is an add-on board designed to fit TI’s MCU LaunchPads. This product allows the software application developer to get familiar with the functionalities of the RF430CL330H on their Texas Instruments embedded microcontroller platform of choice without having to worry about designing the antenna. This document provides direction for RF430CL331H users who wish to implement an NFC tag emulator that is connected to and controlled by a Texas Instruments embedded microcontroller or microprocessor development platform. Examples of such development platforms are the MSP-EXP430G2 LaunchPad and the MSP-EXP430F5529LP LaunchPad. LaunchPads from Texas Instruments are easy-to-use flash programming and debugging tools for the MSP430, C2000, TIVA, etc. lines of microcontrollers. They feature everything you need to start developing on a Texas Instruments microcontroller device. There is on-board emulation for programming and debugging, on-board button switches, LED’s and BoosterPack-compatible pinouts to support a wide range of plug-in modules like the DLP-RF430CL331BP.

Open-source development is also possible thanks to community-driven projects such as the MSPGCC compiler or Energia, a branch of the popular Wiring framework. 2.0 SCOPE This document describes the DLP-RF430CL331BP module for evaluation and development purposes in conjunction with Texas Instruments embedded development platforms. This manual does not cover the in-depth details of the RF430CL331H family as these are documented in the datasheets for those parts along with application notes that can be found on their product pages (see the links in Section 3). 3.0 REFERENCES • • • • DLP-RF430CL331BP Datasheet: www.dlpdesign.com DLP-RF430CL331BP Firmware for LauchPad: http://www.ti.com/lit/zip/sloc330 RF430CL331H Product Page: http://www.ti.com/product/rf430cl331h RF430CL331H Datasheet: http://www.ti.com/lit/ds/symlink/rf430cl331h.pdf 4.0 MODULE DESCRIPTION The DLP-RF430CL331BP BoosterPack allows NFC connection handover for an alternative carrier like Low Energy (BLE) and Wi-Fi as an easy and intuitive pairing or authentication process with only a tap. As a general NFC interface, the RF430CL331H enables electronic products to communicate with the fast-growing infrastructure of NFC-enabled smart phones, tablets and notebooks. Connection to Texas Instruments LaunchPad platforms are made via 10-pin, 0.1-inch spaced, 0.025-square inch female headers located on the back of the board.
