ZigBee SEP 2.0 system-on-chip with integrated ARM Cortex-M3 processor and memory from TI


Dallas, TX, U.S.A. — (METERING.COM) — January 24, 2012 – The first demonstration of a radio frequency (RF) system-on-chip (SoC) that integrates an IEEE 802.15.4 (2.4 GHz) radio, ARM® Cortex™-M3 processor, dedicated Smart Energy 2.0 hardware security acceleration, and enough flash and RAM to run the ZigBee® IP stack and SEP 2.0, has been announced by Texas Instruments.

A true single chip solution, the CC2538 removes the need for an additional microprocessor and will enable simplified, cost effective development of SEP 2.0 compliant smart grid and remote sensor connectivity applications such as electricity, gas or water smart meters and in-home displays.

The CC2538 will support TI’s Z-Stack™ ZigBee protocol stack, which features full SEP 1.1 functionality. The SEP 2.0 is architected to interface with multiple TI PHYs, allowing the design of products that can run across ZigBee, Wi-Fi® or power line networks including TI’s ZigBee processors (CC253x) and WiLink™ 6.0 solutions (WL127x). As the SEP 2.0 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.   

“We are proud to deliver a complete SEP 2.0 platform for early adopters to quickly develop compliant devices without the added cost of a microcontroller or external memory,” said Oyvind Birkenes, general manager, low power RF at TI.

Other recent new products from TI include:

  • The new CC2541 Bluetooth low energy SoC, which delivers longer battery life for sensor applications in home automation and other areas
  • New ZigBee RF4CE solution, which enables interactive connections with consumer electronic devices
  • Expanded OMAP™ 4 mobile processors  to support next generation smart home capabilities in four key categories – 10-foot user interface experiences, family communication, practical home tools and in-home robotics
  • In partnership with metaio and Total Immersion, OMAP-optimized augmented reality (AR) software development kits to implement next generation, interactive AR designs.
