Second generation 2.4 GHz ZigBee/IEEE 802.15.4 RF transceiver - CC2520

CC2520 (ACTIVE)

Second generation 2.4 GHz ZigBee/IEEE 802.15.4 RF transceiver

Description

The CC2520 is TI's second generation ZigBee®/ IEEE 802.15.4 RF transceiver for the 2.4 GHz unlicensed ISM band. This chip enables industrial grade applications by offering state-of-the-art selectivity/co-existence, excellent link budget, operation up to 125°C and low voltage operation.

In addition, the CC2520 provides extensive hardware support for frame handling, data buffering, burst transmissions, data encryption, data authentication, clear channel assessment, link quality indication and frame timing information. These features reduce the load on the host controller.

In a typical system, the CC2520 will be used together with a microcontroller and a few additional passive components.
