1 Introduction

Thank you for purchasing a CC2520 Development Kit.

The CC2520 is Texas Instrument’s second generation ZigBee/IEEE 802.15.4 RF transceiver

for the 2.4 GHz unlicensed ISM band. This chip enables industrial grade applications by

offering state-of-the-art noise immunity, excellent link budget, operation up to 125 degrees

and low voltage operation.

In addition, the CC2520 provides extensive hardware support for packet handling, data

buffering, burst transmissions, data encryption, data authentication, clear channel

assessment, link quality indication and packet timing information. These features reduce the

load on the host controller.

The CC2520 Development Kit includes all the necessary hardware in order to properly

evaluate, demonstrate, prototype and develop software targeting not only 802.15.4 or ZigBee

compliant applications, but also proprietary applications requiring a DSSS radio.

Make sure to subscribe to the Low-Power RF eNewsletter to receive information about

updates to documentation, new product releases and more. Sign up on the Texas

Instruments Low Power Wireless web site www.ti.com/lpw.

2 About this manual

This manual contains reference information about the hardware components of the CC2520

Development Kit.

Chapter 4 will briefly describe the contents of the development kit and chapter 5 will give a

quick introduction to how to get started with the kit. In particular, it describes how to install

SmartRF Studio to get the required drivers for the evaluation board, how the hardware can be

used and mentions the software that is available for the development kit. Chapter 6 explains

some simple methods for performing practical RF testing with the development kit. Chapter 7,

8 and 9 describe in detail the hardware that can be found in the kit. A troubleshooting guide

can be found in chapter 10. Appendix A and B contain the schematics for the SmartRF05EB

and CCMSP-EM430F2618 respectively.

The CC2520DK Quick Start Guide (www.ti.com/lit/swru139) has a short tutorial on how to get

started with the kit. The CC2520 Software User’s Guide (www.ti.com/lit/swru137) has details

about the software examples and information about other software options for the CC2520.

The PC tools SmartRF®Studio and SmartRF®Flash Programmer have their own user

manuals.

Please visit the kit web page on www.ti.com/cc2520dk for additional information.

See chapter 11 for a list of relevant documents and links.

4 Development Kit contents

The CC2520 Development Kit includes hardware and software that allows quick testing of the

CC2520 RF performance and offers a complete platform for development of advanced

prototype RF systems.

•Evaluate the CC2520 right out of the box. The kit can be used for range testing using the

pre-programmed PER tester running on the MSP430F2618.

•Use SmartRF Studio to perform RF measurements. The radio can be easily configured to

measure sensitivity, output power and other RF parameters.

•Prototype development. All I/O from the CC2520 are available on pin connectors on the

SmartRF05EB and on the CCMSP-EM, allowing easy interconnection to other devices or

controllers.

The development kit contains the following components

•3 x SmartRF®05EB

•3 x CC2520EM evaluation modules

•3 x Antennas

•2 x CCMSP-EM430F2618

•1 x MSP-FET430UIF debug interface

•3 x USB cables

•Documents

SmartRF05EB

The SmartRF05EB (Evaluation Board) is the main

board in the kit with a wide range of user

interfaces:

•3x16 character serial LCD

•Full speed USB 2.0 interface

•UART

•LEDs

•Serial Flash

•Potmeter

•Joystick

•Buttons

The EB is the platform for the evaluation modules

(EM) and can be connected to the PC via USB to

control the EM.

CCMSP-EM430F2618

This is a generic microcontroller board with an

MSP430F2618. The MCU Board can be plugged

into the SmartRF05EB and it is compatible with

most TI LPW RF-IC EMs.

CC2520EM

This is the CC2520 Evaluation Module (EM) with

the RF IC and necessary external components

and matching filters for getting the most out of the

radio. The module can be plugged into the

SmartRF05EB directly for control from SmartRF

Studio or into the CCMSP-EM430F2618 for

control from MSP430. Use the EM as reference

design for antenna and RF layout.

MSP-FET430UIF

This is the MSP430 USB Debug Interface for

programming and debugging applications running

on the MSP430F2618. It connects to the PC via

USB and uses JTAG to communicate with the

microcontroller.

5 Getting started

Please refer to the CC2520DK Quick Start Guide (www.ti.com/lit/swru139) for a short

introduction on how to use the kit.

5.1 SmartRF Studio

SmartRF Studio is a PC application developed for configuration and evaluation of many of the

RF-IC products from Texas Instruments, including the CC2520. The application is designed

for use with an applicable SmartRF evaluation board, such as the SmartRF05EB, and runs on

Microsoft Windows.

SmartRF Studio lets you explore and gain knowledge about the CC2520 as it gives you full

overview and access to the RF-IC’s registers to configure the radio and has a control

interface for simple radio operation from your PC.

This means that SmartRF Studio will help radio system designers to easily evaluate the RF-IC

at an early stage in the design process. It also offers a flexible code export function of radio

The latest version of SmartRF Studio can be downloaded from the Texas Instruments website

(www.ti.com/smartrfstudio), where you will also find a complete user manual.

5.2 Installing SmartRF Studio and Windows drivers

Before your PC can communicate with the SmartRF05EB over USB, you will need to install

the driver files for the EB. The latest SmartRF Studio installer includes drivers for Windows.

A brief set of installation instructions for Microsoft Windows XP will be given here, but also

Windows 2000, Windows NT and Windows 98 are supported. Please consult the SmartRF

Studio User Manual for further details or the troubleshooting section if needed.

After you have downloaded the SmartRF Studio from the web, extract the zip-file, run the

installer file and follow the instructions. Pick a complete installation to include the SmartRF

Studio program, the SmartRF Studio documentation and the necessary Windows drivers

needed to communicate with the SmartRF05EB.

You can now connect your SmartRF05EB to the computer with a USB cable and turn it on. A

“Found New Hardware” dialog box will prompt you to locate the missing driver.

It is highly recommended to install SmartRF Studio before you

connect the SmartRF05EB to the computer.

Figure 2 - Connecting the SmartRF05EB for the first time (Windows XP)

If you did a complete install of SmartRF Studio, the driver to use is already copied to your

hard drive. Select “No, not this time” and continue with “Next”.

Figure 3 - Select automatic installation of software (Windows XP)

swru138

9/33

Select “Install the software automatically” to install the driver for the SmartRF05EB. Windows

should automatically find the location of the driver to use. If unsuccessful, go back and

manually specify to look in specific location and select the directory C:\Program Files\Texas

Instruments\Extras\Drivers for the needed *.inf and *.sys driver files.

Figure 4 - The driver installation is completed (Windows XP)

The driver is now installed and the computer should be ready for use with SmartRF Studio.

You can verify that the driver is properly installed by opening the Device Manager and see

that when the EB is connected the “Cebal controlled devices” list contains “SmartRF05EB”

and that it is not labelled with an exclamation mark.

Figure 5 - Properly installed SmartRF05EB software (Windows XP)

When launching SmartRF Studio, the evaluation board should now appear in the SmartRF05

DK tab. Double click on the device, and a new window opens – giving access to all of the

registers on the chip as well as making it possible to perform various RF test.
