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.
● 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
● Applications
● 2400-2483.5 MHz ISM/SRD band systems
● Consumer Electronics
● Wireless game controllers
● Wireless audio
● Wireless keyboard and mouse
● RF enabled remote controls
