TI Introduces New Zigbee-based SoC

24 Jan 2012

Texas Instruments has presented the industry’s first demonstration of a radio frequency (RF) system-on-chip (SoC) that the company reports “integrates an IEEE 802.15.4 (2.4 GHz) radio, an ARM Cortex-M3 processor, dedicated Smart Energy (SE) 2.0 hardware security acceleration, and enough flash and RAM to run the ZigBee IP stack and SE2.0 profile.”

Billed as a true single-chip solution, the CC2538 ZigBee SE2.0 SoC eliminates the need for an additional microprocessor and enables the development of SE2.0 compliant Smart Grid as well as remote sensor connectivity applications such as electricity, gas or water smart meters and in-home displays.
As the SE2.0 market expands this will enable customers to use ZigBee or Wi-Fi to connect to existing and new infrastructure or use Wi-Fi as a bridge for ZigBee to connect to the Internet.

Oyvind Birkenes, TI’s general manager of low-power RF, says, “We are proud to deliver a complete SE2.0 platform for early adopters to quickly develop SE2.0 compliant devices without the added cost of a microcontroller or external memory. Our team has been instrumental in the development and technical editing of the SE2.0 IP stack and profile within the ZigBee Alliance and we are excited to see the market evolve with new products based on TI’s CC2538 SE2.0 SoC and CC1200 for sub-1 GHz solutions.”

TI, which has shipped millions of energy meter ICs shipped over the past decade, provides the industry’s broadest portfolio of mature wireless connectivity solutions along with metrology expertise, application processors, communication systems, wireless connectivity and analog components in readily available silicon, with advanced software, tools and support for compliant solutions in grid infrastructure, utility metering, and home or building automation.
