Texas Instruments' CC2520 ZigBee/IEEE 802.15.4 transceiver for 2.4 GHz band applications delivers state-of-the-art selectivity/co-existence and excellent link budget.
The chip can be used in a wide variety of standard-based and proprietary wireless systems for industrial monitoring and control, home and building automation, set-top boxes, remote controls and wireless sensor networks.
In a typical system, the CC2520 will be teamed with a microcontroller such as TI's MSP430 and a few passive components.
The CC2520 reduces the load on the host controller by providing support for packet handling, data buffering, burst transmissions, data encryption, data authentication, clear channel assessment, link quality indication and packet timing information.
Key CC2520 specifications include 1.8 V to 3.8 V supply range, -40C to +125C temperature range, 103 dB link budget (400 m line-of-sight range with the development kit), 50 dB adjacent channel rejection. The CC2520 provides an easy upgrade path for the CC2420 RF transceiver.
The CC2520 is available now from TI and its authorized distributors in 5 mm x 5 mm QFN-28 package. Suggested resale pricing for the CC2520 starts at $3.10 each in 100-unit quantities. A development kit (CC2520DK) includes both hardware and software for advanced prototyping.
