DESCRIPTION  
QFN28 (RHD) PACKAGE  
TOP VIEW  
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.
