    Features of CC2500:

    • RF Performance
      • High sensitivity (-104 dBm at 2.4 kBaud, 1% packet error rate)
      • Low current consumption (13.3 mA in RX, 250 kBaud, input well above sensitivity limit)
      • Programmable output power up to 1 dBm
      • Excellent receiver selectivity and blocking performance
      • Programmable data rate from 1.2 to 500 kBaud
      • Frequency range: 2400 - 2483.5 MHz
    • Analog Features
      • OOK, 2-FSK, GFSK, and MSK supported
      • Suitable for frequency hopping and multichannel systems due to a fast settling frequency synthesizer with 90 us settling time
      • Automatic Frequency Compensation (AFC) can be used to align the frequency synthesizer to the received centre frequency
      • Integrated analog temperature sensor
    • Digital Features
      • Flexible support for packet oriented systems: On-chip support for sync word detection, address check, flexible packet length, and automatic CRC handling
      • Efficient SPI interface: All registers can be programmed with one "burst" transfer
      • Digital RSSI output
      • Programmable channel filter bandwidth
      • Programmable Carrier Sense (CS) indicator
      • Programmable Preamble Quality Indicator (PQI) for improved protection against false sync word detection in random noise
      • Support for automatic Clear Channel Assessment (CCA) before transmitting (for listen-before-talk systems)
      • Support for per-package Link Quality Indication (LQI)
      • Optional automatic whitening and dewhitening of data
    • Low-Power Features
      • 400 nA SLEEP mode current consumption
      • Fast startup time: 240 us from SLEEP to RX or TX mode (measured on EM design)
      • Wake-on-radio functionality for automatic low-power RX polling
      • Separate 64-byte RX and TX data FIFOs (enables burst mode data transmission)
    • General
      • Few external components: Complete onchip frequency synthesizer, no external filters or RF switch needed
      • Green package: RoHS compliant and no antimony or bromine
      • Small size (QLP 4x4 mm package, 20 pins)
      • Suited for systems compliant with EN 300 328 and EN 300 440 class 2 (Europe), FCC CFR47 Part 15 (US), and ARIB STDT66 (Japan)
      • Support for asynchronous and synchronous serial receive/transmit mode for backwards compatibility with existing radio communication protocols

    These evaluation modules in combination with a motherboard from a CC2500 development kit is designed to help the user to achieve his/hers objectives as quickly as possible.

    This evaluation kit includes 2 CC2500EM evaluation modules and antennas. These evaluation modules are add-on daughter boards that require a CC2500 development kit for evaluation and development.

    Evaluate the SmartRF®04 products. Right out of the box, the user can do range testing (PER testing) and transfer data from one PC to another using the SmartRF®04DK. This enables the user to quickly find out how well the SmartRF®04 products fit the intended application. A number of demonstration applications serve to highlight the innovative features of the SmartRF®04 ICs.

    Perform RF measurements. Using SmartRF® Studio, the user can configure the radio ICs with parameters that suit the intended application and easily measure sensitivity output power and other RF parameters.

    Develop a prototype. The SmartRF®04DK includes a a Silicon Labs 8051 core MCU with 16 kB of program memory and 1 kB of data memory. By programming this MCU and utilizing the various peripherals included on the Evaluation Board, the user can easily make a prototype of the intended application. All signals are brought out on 0.1" pin-row connectors so easy connection of other required circuity is possible. These connectors are also compatible with Agilent logic analyser probes for easy debugging. It is also possible to disconnect the Silicon Labs MCU from the EM board, and connect a MCU selected by the user to the I/O connectors.

    Applications:

    • 2400-2483.5 MHz ISM/SRD band systems
    • Consumer Electronics
