Low Cost, Low-Power 2.4 GHz RF Transceiver Designed for Low-Power Wireless Apps in the 2.4 GHz ISM B

Description

The CC2500 is a low-cost 2.4 GHz transceiver designed for very low-power wireless applications. The circuit is intended for the 2400-2483.5 MHz ISM (Industrial, Scientific and Medical) and SRD (Short Range Device) frequency band.

The RF transceiver is integrated with a highly configurable baseband modem. The modem supports various modulation formats and has a configurable data rate up to 500 kBaud.

CC2500 provides extensive hardware support for packet handling, data buffering, burst transmissions, clear channel assessment, link quality indication and wake-on-radio.

The main operating parameters and the 64-byte transmit/receive FIFOs of CC2500 can be controlled via an SPI interface. In a typical system, the CC2500 will be used together with a microcontroller and a few additional passive components.

Features

    • 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
