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
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.
