The circuit is intended for the 2400-2483.5 MHz ISM (Industrial,Scientific andMedical)andSRD(ShortRangeDevice)frequency band.The RF transceiver is integrated with a highlyconfigurable baseband modem. The modemsupports various modulation formats and hasa configurable data rate up to 500 kBaud.CC2500provides extensive hardware supportforpackethandling,databuffering,bursttransmissions, clear channel assessment, linkquality indication, and wake-on-radio.The main operating parameters and the 64-byte transmit/receive FIFOs ofCC2500can becontrolled via an SPI interface. In a typicalsystem, theCC2500will be used together witha microcontroller and a few additional passivecomponents.6789102019181716Key FeaturesRF PerformanceHigh sensitivity (–104 dBm at 2.4 kBaud,1% packet error rate)Low current consumption (13.3 mA in RX,250 kBaud, input well above sensitivitylimit)Programmable output power up to +1 dBmExcellent receiver selectivity and blockingperformanceProgrammable data rate from 1.2 to 500kBaudFrequency range: 2400 – 2483.5 MHzAnalog FeaturesOOK, 2-FSK, GFSK, and MSK supportedSuitable for frequency hopping and multi-channel systems due to a fast settlingfrequency synthesizer with 90 us settlingtimeAutomaticFrequencyCompensation(AFC) can be used to align the frequencysynthesizertothereceivedcentrefrequencyIntegrated analog temperature sensorDigital FeaturesFlexiblesupportforpacketorientedsystems: On-chip support for sync worddetection, address check, flexible packetlength, and automatic CRC handlingEfficient SPI interface: All registers can beprogrammed with one “burst” transferDigital RSSI outputProgrammable channel filter bandwidthProgrammableCarrierSense(CS)indicator
