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 datarate of
250 kbps.
controller and allow CC2420 to interface
low-cost microcontrollers.
The configuration interface and transmit /
receive FIFOs of CC2420 are accessed via
a SPI interface. In a typical application
CC2420 will be used together with a
microcontroller and a few external passive
components.
The CC2420 is a low-cost, highly integrated
solution for robust wireless communication
in the 2.4 GHz unlicensed ISM band. It
complies with world-wide regulations
covered by EN 300 440 (Europe), CFR47
Part 15 (US) and ARIB STD-T-66 (Japan).
CC2420 is based on Chipcon’s SmartRF®-
03 technology in 0.18 µm CMOS.
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
