 Consumer electronics

 Wireless game controllers

 Wireless audio

 Wireless keyboard and mouse

 RF enabled remote controls

Product Description

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.

Key Features

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)
