ZigBee and zigBee-PRO
Modules were engineered to meet ZigBee/IEEE 802.15.4 standards and support the
unique needs of low-cost, low-power wireless sensor networks. The modules
require minimal power and provide reliable delivery of critical data between
devices. The modules operate within the ISM 2.4 GHz frequency band and are
pin-for-pin compatible with each other.
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.
