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
