TI Delivers Industry's First Location Detection System-on-Chip for ZigBee(R) Wireless Sensor Networking

June 19, 2007

Highly Integrated Device Accurately Calculates Location in
Mesh Networks
		

    DALLAS, June 19 /Xinhua-PRNewswire/ -- Texas
Instruments Incorporated (TI) (NYSE: TXN) today introduced
the industry's first System-on-Chip (SoC) solution with a
hardware location engine targeting low-power ZigBee(R)/IEEE
802.15.4 wireless sensor networking applications. The
CC2431, from the company's Chipcon product line, targets
applications such as asset and equipment tracking,
inventory control, patient monitoring, remote controls,
security and commissioning networks. The device is
supported by TI's leading ZigBee protocol stack,
Z-Stack(TM). (See http://www.ti.com/cc2431-pr .)

    The CC2431 is based on the industry's first available
SoC solution for low-power RF applications, the CC2430.
Both devices combine the excellent performance of the
industry-leading CC2420 RF transceiver core with an
enhanced 8051 microcontroller, up to 128 kB flash memory, 8
kB of RAM and many additional features -- all in a small 7mm
x 7mm package.

    The CC2431's RSSI-based location engine accurately
calculates the node's position based on the receive signal
strength from CC2430-based reference nodes with known
locations and can then send the location information to a
collector (e.g. computer, PDA, handset). This capability
reduces network traffic and communication delays compared
to centralized location systems. In typical applications,
accuracy of 3-5 meters can be achieved.

    "Combined with the Z-Stack, the CC2431 provides
the market's most competitive ZigBee solution and
illustrates the innovation and market leadership of the
Chipcon product line," said Art George, senior vice
president of TI's high-performance analog business.
"Customers will now be able to develop reliable and
robust wireless networks, while reducing time-to-market and
minimizing production costs."

    TI's Z-Stack protocol software is designed to the
ZigBee 2006 specification and supports multiple platforms,
including the CC2431, CC2430 and CC2420+MSP430 platform.
The Z-Stack has been awarded the ZigBee Alliance's golden
unit status by the ZigBee test house TUV Rheinland and is
used by thousands of ZigBee developers worldwide. The
Z-Stack is available for free downloading at

    Availability and Packaging

    The CC2431 is sampling now, with volume production
scheduled for 3Q 2007. The device is available in a
RoHS-compliant 7mm x 7mm QLP-48 package and is priced at
$6.45 in 1,000-piece quantities (suggested resale pricing).
The CC2430 is in volume production and available from TI and
its authorized distributors. Start your development today
