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.
