Приёмо-передатчик общего назначения CC2520RHDT .

RF Transceiver , Zigbee, 2.394GHz to 2.507GHz, DSSS, 1.8V to 3.8V, 5dBm Out/-98dBm In, QFN-28

The CC2520RHDT is a second generation ZigBee/IEEE 802.15.4 RF Transceiver for the 2.4GHz 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 transceiver will be used together with a microcontroller and a few additional passive components.
