Overview
The CC2520RHDR is Texas Instruments' second-generation ZigBee®/IEEE 802.15.4 RF transceiver, designed for the 2.4 GHz unlicensed ISM band. This chip is tailored for industrial-grade applications, offering state-of-the-art selectivity and co-existence, an excellent link budget, and operation up to 125°C. It also supports low-voltage operation and extensive hardware support for frame handling, data buffering, burst transmissions, data encryption, and authentication. The CC2520 is typically used in conjunction with a microcontroller and a few additional passive components.
