CC2431RTCR

Product Summary

The CC2431RTCR is a true System-On-Chip (SOC) for wireless sensor networking ZigBee/IEEE 802.15.4 solutions. The chip includes a location detection hardware module that can be used in so-called blind nodes (i.e. nodes with unknown location) to receive signals from nodes with known location’s. Based on this the location engine calculates an estimate of a blind node’s position. The CC2431RTCR enables ZigBee nodes to be built with very low total bill-of-material costs. The applications of the CC2431RTCR include ZigBee systems, 2.4 GHz IEEE 802.15.4 systems, Home/building automation, Industrial Control and Monitoring, Low power wireless sensor networks, Access Control, PC peripherals, Set-top boxes and remote controls, Consumer Electronics, Container/Vehicle Tracking, Active RFID, Inventory Control.
