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.
