CC2500
Low-Cost Low-Power 2.4 GHz RF Transceiver
Applications
 2400-2483.5 MHz ISM/SRD band systems
 Consumer electronics
 Wireless game controllers
Product Description
The CC2500 is a low-cost 2.4 GHz transceiver
designed for very low-power wireless appli-
cations. 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
 Wireless audio
 Wireless keyboard and mouse
 RF enabled remote controls
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 multi-
channel 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)
