The
●CC2431
● 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 locations. Based on this the location engine calculates an estimate of a blind nodes position. The
●CC2431
● enables ZigBee® 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 ZigBee® protocol stack (Z-Stack™) from Texas Instruments, the
●CC2431
● provides the markets most competitive ZigBee® solution.
●The
●CC2431
● is highly suited for systems where ultra low power consumption is required. This is achieved by various operating modes. Short transition times between these modes further ensure low power consumption.
