Texas Instruments announces the demonstration of a radio frequency system-on-chip that integrates an IEEE 802.15.4 (2.4 GHz) radio, an ARM Cortex-M3 processor, dedicated Smart Energy 2.0 hardware security acceleration, and enough flash and RAM to run the ZigBee IP stack and SE2.0 profile. A true single-chip solution, the CC2538 ZigBee SE2.0 SoC removes the need for an additional microprocessor and will enable simplified, cost-effective development of SE2.0 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 SE1.1 functionality. The SE2.0 profile is architected to interface with multiple TI PHYs, allowing the design of SE2.0 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 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. Also being demonstrated at DistribuTECH 2012 is TI’s high performance CC1200 RF transceiver. The CC1200, an evolution of the CC1120 sub-1 GHz RF performance line, supports the full bandwidth of the 802.15.4g standard for wireless smart utility networks in the sub-1 GHz bands.
