2.4 GHz IEEE 802.15.4 / ZigBee-ready RF Transceiver
 
Applications 
•  2.4 GHz IEEE 802.15.4 systems 
•  ZigBee systems 
•  Home/building automation 
•  Industrial Control 
•  Wireless sensor networks 
•  PC peripherals 
•  Consumer Electronics
Product Description 
The
 CC2420
 is a true single-chip 2.4 GHz 
IEEE 802.15.4 compliant RF transceiver 
designed for low power and low voltage 
wireless applications. 
CC2420
 includes a 
digital direct sequence spread spectrum 
baseband modem providing a spreading 
gain of 9 dB and an effective data rate of 
250 kbps. 
The 
CC2420
 is a low-cost, highly integrated 
solution for robust wireless communication 
in the 2.4 GHz unlicensed ISM band. It 
complies with worldwide regulations 
covered by ETSI EN 300 328 and EN 300 
440 class 2 (Europe), FCC CFR47 Part 15 
(US) and ARIB STD-T66 (Japan).   
The 
CC2420
 provides extensive hardware 
support for packet handling, data 
buffering, burst transmissions, data 
encryption, data authentication, clear 
channel assessment, link quality indication 
and packet timing information. These 
features reduce the load on the host 
controller and allow 
CC2420
 to interface 
low-cost microcontrollers. 
The configuration interface and transmit / 
receive FIFOs of 
CC2420
 are accessed via 
an SPI interface. In a typical application 
CC2420
 will be used together with a 
microcontroller and a few external passive 
components. 
CC2420
 is based on Chipcon’s SmartRF

-
03 technology in 0.18 
µm CMOS.
