CC2500
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)
indicator

CC2500
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 de-
whitening 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)
General
Few external components: Complete on-
chip 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 STD-
T66 (Japan)
Support for asynchronous and
synchronous serial receive/transmit mode
for backwards compatibility with existing
radio communication protocols
