SWRA276A March 2013 CC2531 USB Evaluation Kit Quick Start Guide 1. Kit Contents  1 x CC2531 USB Dongle  Documentation The RF boards in this kit are FCC and IC certified and tested to comply with ETSI/R&TTE over temperature from 0 to +35°C. Caution! The kit contains ESD sensitive components. Handle with care to prevent permanent damage. 2. Getting Started The CC2531 USB Dongle can be used as a development platform for USB and RF applications. An external development tool, like the CC Debugger, is required to program and debug software running on the CC2531. The CC2531 Dongle comes preprogrammed with software that lets the dongle operate as a packet capture device for the SmartRF Packet Sniffer. This Quick Start Guide will describe how to use the dongle with the packet sniffer and the next steps for your own software development. 3. Install the driver Before plugging the dongle into the PC, please install TI’s SmartRF Packet Sniffer. When installing the Packet Sniffer, you will also automatically install the USB driver required for proper communication between the dongle and the packet sniffer. The Packet Sniffer can be downloaded from www.ti.com/tool/packet-sniffer 4. Insert the USB dongle When inserting the USB dongle into a USB slot, Windows’ new hardware wizard will appear. Select the options for automatic installation and wait for the driver installation to complete. After installation, the Packet Sniffer is ready for use. Caution! This USB dongle has been designed to be powered from a USB port. Do not attempt to connect other power sources to the device. Avoid powering the unit when not in use. 5. Packet Sniffer TI’s SmartRF Packet Sniffer is a convenient tool for debugging of RF protocols. It displays the captured packets and decodes the packet contents depending on what protocol you are running. When starting the packet sniffer, select the protocol as required. The Packet Sniffer for CC2531 supports SimpliciTI, RemoTI and ZigBee PRO, in addition to a generic mode (no packet parsing). 6. Debugging and Programming For software development on the CC2531 an external debugger is necessary. This can be either a SmartRF05EB [3] as shown in the first picture, ...or a CC Debugger [4] as shown in the second picture. SWRA276A March 2013 7. Flash Programmer Texas Instruments has a simple tool which can be used to program the flash on the CC2531. The Flash Programmer application, available on the kit web page [3], can be used to program Intel HEX files, read the contents of flash and several other operations. You will need a SmartRF05EB, a CC Debugger or other programmers from Third Parties [5] to program the device. 8. IAR Embedded Workbench To develop software and debug software running on the CC2531, you should use IAR Embedded Workbench for 8051. A free, code size limited version can be downloaded from the web. See www.iar.com/ew8051. 9. Thank You! We hope you will enjoy working with the CC2531 and associated Low-Power RF products from Texas Instruments. A.

Operational Description

Texas Instruments Norway AS Gaustadalléen 21 0349 Oslo Norway (+47) 22 95 85 44 (+47) 22 95 85 46 Page 1 of 1 Technical Description The CC2531Dongle is an evaluation board for the CC2531 chip from Texas Instruments. The board is powered through USB. The CC2531System on Chip has a differential RF output. On the CC2531Dongle board this differential output is transformed to a single ended, 50 ohm signal through an integrated balun from Johansson Technologies (2450BM15A0002). Additionally the balun has integrated filter components which greatly reduces harmonic radiation. The single ended output of the balun is connected to an on-board PCB antenna.

RF Exposure Info

SAR Exemption FCC ID.: ZAT2531USB Applicant: Texas Instruments, Inc. Type of Device: USB Dongle Analysis: The product is a USB dongle that is used for development of rf transmitter circuits and software. The device is part of an Evaluation Module (EVM) kit and is intended only for use by developers. Since the dongle could be used in any laptop computer and a specific minimum separation distance cannot be determined, the minimum separation of 5 mm is used per 447498 10 D01 General RF Exposure Guidance v05. The SAR exclusion is calculated using the formula from page 10 of 447498 10 D01. From test report 182230‐5, issued by Nemko AS, the maximum measured rf output power is 4.47 mW. Therefore: ൤ ܹ݉5 ݉݉5 ൨െ √ 2.4ൌ1െ1.5ൌ െ0.5 This is below the threshold of 3.0 for 1‐g SAR and 7.5 for 10‐g SAR.
