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.
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
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
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
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)
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
