CC2431
System-on-Chip for 2.4 GHz ZigBee^®/ IEEE 802.15.4 with Location Engine
Applications
• ZigBee^® systems
• 2.4 GHz IEEE 802.15.4 systems
• Home/building automation
• Industrial Control and Monitoring
• Low power wireless sensor networks
• Access Control
Product Description
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 location’s. Based on this the
location engine calculates an estimate of a
blind node’s 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 market’s
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.
