The CC2431 is a true System-On-Chip (SOC) for wireless sensor networking ZigBeeTM / 802.15.4 solutions with location detection engine hardware onboard allowing location accuracy of around 3 meters or less. It enables ZigBeeTM nodes to be built with very low total bill-of-material costs. The CC2431 combines the excellent performance of the leading CC2420 RF transceiver with an industry-standard enhanced 8051 MCU, 128 KB flash memory, 8 KB RAM and many other powerful features. Combined with the industry leading ZigBeeTM protocol stack (Z-StackTM) from Figure 8 Wireless / Chipcon, the CC2431 provides the market's most competitive ZigBeeTM solution.
