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.

Free software development tools are also available, such as TI’s Eclipse-based Code Composer Studio.
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).

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. The electrical schematic is
available for download from www.dlpdesign.com.

6.0 QUICK START GUIDE
If using Code Composer to load, edit and compile the demonstration firmware:
1. Remove jumper P1.6 from the G2 LaunchPad.
2. Attach the G2 LaunchPad to the DLP-RF430CL331BP as shown here.
3. Apply power by connecting a USB cable to the LaunchPad.
4. Load (Import) the base application firmware into Code Composer Studio. The firmware project is
available for download from this link: http://www.ti.com/lit/zip/sloc330
5. Enter Debug mode and test for basic functionality by holding an NFC-enabled smart phone, tablet or
notebook close to the onboard loop antenna. The device should display "Hello, world!" for the default
NDEF message.
6. Modify the source code as desired to change the default message.
