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

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

Key Features

•True single-chip 2.4 GHz IEEE 802.15.4 compliant RF transceiver with baseband modem and MAC support

•DSSS baseband modem with 2 MChips/s and 250 kbps effective data rate.

•Suitable for both RFD and FFD operation

•Low current consumption (RX: 18.8

mA, TX: 17.4 mA)

•Low supply voltage (2.1 – 3.6 V) with integrated voltage regulator

•Low supply voltage (1.6 – 2.0 V) with external voltage regulator

•Wireless sensor networks

•PC peripherals

•Consumer Electronics

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 ∝m CMOS.
