  • 2.4 GHz – (virtually) world-wide frequency band Sub-1 GHz bands are different in different parts of the world US, Canada use FCC rules EU 433/868 is (mostly) harmonized throughout Europe 426 MHz ARIB in Japan – very strict narrowband requirements, similar regulations in Korea Rest of world has available frequency bands on a country-by-country basis
  • The recommended setting is 4-byte preamble and 4-byte sync word, except for 500 kBaud data rate where the recommended preamble length is 8 bytes. Fixed Packet Length Mode: PKTCTRL0.LENGTH_CONFIG=00 PKTLEN register indicates the packet length
  • We are very proud to introduce the next generation in easy to use development tools, the eZ430-RF2500. Following on the success of the original eZ430-F2013, TI’s best selling development tool in history, the eZ430-RF2500 is based on the high-end MSP430F2274 featuring 32k Flash, 1k RAM, 200ksps 12-bit ADC12, USCI (SPI, UART/LIN, IrDA, I2C), and 3x OpAmps and a CC2500, a 2.4 GHz, 4th Generation Low Power wireless transceiver. 18-pins selected pins on the F2274 are available on the target, 2 LEDs for visual feedback, and a push-button for user interface. Just like the original eZ430, full in-system debug is possible through the 2-wire Spy Bi-Wire interface, however, this features a next generation emulator which features a driverless installation. The entire system ready to go within seconds of being plugged into your PC without the need to install any software. Also, the emulator has been enhanced to allow communication from the F2274 target through USB to a virtual COM port. So it will be possible to have a wireless system collecting data which can transmit it back to your PC which can be displayed in a real application with your debugger closed. SimpliciTI, a full, low power, star network stack will be available for the tool and will support up to 254 wireless nodes, various low power modes, network coordinators, range extenders and end devices. A temperature sensor network demonstration application will come with the tool showing the capability and provide a starting point for you to being your wireless applications. At $49 USD, the eZ430-RF2500 will include one emulator and target board with an enclosure and an additional target board with a battery expansion board for immediate deployment. This is the lowest priced RF development tool on the market and standalone target boards (eZ430-RF2500T) will also be available by launch time. Note: Pictured above are early prototypes. Final hardware will vary in color and include an enclosure.
  • It’s now easy to rev up your application in minutes with the new eZ430-RF2500 , the world’s smallest complete wireless development tool for only $49! The tool provides all hardware and software needed to evaluate the MSP430 or complete an entire F22xx project. The eZ430-RF2500 includes three tiny PCB boards, one emulation board and two detachable wireless target, connected with a 6-pin connector and encased in USB stick case. A tiny battery expansion board and 2 AAA batteries are also included for easy deployment of your wireless system. The MSP430 Tools CD-ROM is also included. . The eZ430-RF2500T target board include an MSP430F2274, a CC2500, a 26MHz oscillator for the radio and a small chip antenna. Additionally two LEDs (red and green) are provided for immediate feedback and a tiny interruptible pushbutton for user interaction. 18 carefully selected pins from the F2274 are accessible on the target on convenient a 0.1” centered though hole header and 4 additional pins are available when paired with the battery expansion board. The needed IAR KickStart Embedded Workbench IDE software and a demonstration project are provided on the included MSP430 Tools CD-ROM. IAR KickStart as well as 100’s of code examples and other support are available for free from TI’s website. The eZ430 uses the same IAR IDE as all other MSP430s so there is nothing new to learn. Complete wireless network stacks such as TI’s SimpliciTI network protocol, also come with the tool and provide developers a complete starting point to develop a working wireless solution out of the box.
  • Because the eZ430 target board can be disconnected from the emulation interface, the complete tool is much more than a demo or evaluation system. An entire MSP430 project equipped with Spy Bi-Wire, including the original eZ430-F2013 and T2012 target boards, can be developed using just the eZ430-rf. Competing basic demo or evaluation systems contain the emulation and target device on a single board preventing a stand alone project implementation. The emulation interface can not be separated from the target device. Only simple demonstrations or limited evaluation are possible. The detachable RF target board can be used as a stand alone system and through its many interfaces and peripherals both analog and digital, it may be used to wirelessly enable any existing design as an off-the-shelf wireless module. It could also be used as an wireless independent data sampling system such as an environmental wireless sensor network or home automation system.
