TI achieves certification of ZigBee Allianceís Smart Energy 1.1 profile implementation

TIís new Z-Stack 2.5.0 will help developers easily, efficiently unleash a wider range of interoperable, consumer-friendly home area network products

DALLAS (August 3, 2011) – Texas Instruments Incorporated (TI) today announced that it achieved ZigBee Certified status for its ZigBee Smart Energy 1.1 standard implementation, recently introduced by the ZigBee Alliance. TI is pleased to announce the availability of its new Z-Stack 2.5.0 with support for ZigBee Smart Energy 1.1, geared towards home area networks (HAN). Proving its leadership in the development of low-power wireless applications such as industrial monitoring and control, smart metering, building automation and more, TI's ZigBee Smart Energy 1.1 profile gives developers the confidence and means necessary to interoperate with various implementations. TI’s Z-Stack 2.5.0 with ZigBee Smart Energy 1.1 is available royalty-free to all using TI’s ZigBee-compliant hardware platforms. For more information, visit

“TI is committed to staying ahead of the game in the connectivity space, and we are thrilled to provide our customers with the latest features of ZigBee Smart Energy 1.1,” said Laurent Giai-Miniet, managing director, Low-Power RF business unit, TI. “Our new Z-Stack 2.5.0 will unleash a wider range of interoperable, consumer-friendly HAN products for monitoring things such as energy consumption – a key requirement for the U.S. Department of Energy Smart Grid program and initiatives out of the European Union. We will also continue to deliver Smart Energy-compliant software for future generations, including the forthcoming SEP 2.0.”

“As a leader in the Smart Grid industry, Sensus is pleased to work with TI in driving greener utilities and energy production worldwide,” said David Ayers, vice president of engineering at Sensus. “The Sensus  iCON smart meters use Smart Energy 1.1 to deliver information that helps consumers make better decisions on when and how they can save energy. This is a pivotal step in smarter energy consumption, and – together with TI – we are dedicated to continued advancements in this space.”

TI’s products and rich history in the ZigBee market

TI’s Z-Stack is an industry-leading, Golden-Unit status ZigBee protocol stack, aimed at the growing portfolio of IEEE 802.15.4 products and platforms. The protocol is compliant with the ZigBee 2007 specification, supporting both ZigBee and ZigBee PRO feature sets on various TI hardware platforms such as the CC2530 system-on-chip, ultra-low-power MSP430 microcontroller + CC2520 transceiver, and Stellaris Cortex-M microcontroller + CC2520 transceiver. The high-performance radios feature excellent coexistence with Wi-Fi and Bluetooth technologies, along with other 2.4GHz-based solutions.

With more than 15 years in the smart metering market, TI delivers leading-edge system products, software and tools for grid infrastructure, utility metering, power line communications (PLC), and home and building automation development. TI delivers state-of-the art ZigBee solutions for smart grid and other markets, and will continue to bring new ZigBee developments to market in the future.

Tools, availability, packaging and price

The Z-Stack 2.5.0 is available today from TI’s website, royalty-free to all using TI’s ZigBee compliant hardware platforms. TI’s ZigBee development kits are available on TI’s e-store. The kits contain additional nodes for experimenting with the mesh capabilities of ZigBee, and are preprogrammed with a ZigBee demo application, giving customers ZigBee directly out of the box. A specific kit also demonstrates the concept with a CC2530 running the Z-Stack and a small MSP microcontroller running the application code.
