Zigbee 2.4GHZ 8051 system on chip w. location engine (4
Zigbee® 2.4GHz 8051 System-On-Chip
• 2.4 GHz IEEE 802.15.4 systems
• Industrial Control and Monitoring
• Low power wireless sensor networks
• Set-top boxes and remote controls
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.
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.
