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