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
