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

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
 Wireless audio
