Texas Instruments has demonstrated a RF system-on-chip (SoC) device that integrates an IEEE 802.15.4 (2.4 GHz) radio, an ARM Cortex-M3 processor with Smart Energy (SE) 2.0 hardware security acceleration.
There is flash and RAM on chip to run the ZigBee IP stack and SE2.0 profile.
The chip firm is positioning the chip for the 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.
“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,” said Oyvind Birkenes, general manager, low-power RF, TI.
TI has a CC1200 RF transceiver which supports the full bandwidth of the 802.15.4g standard for wireless smart utility networks in the sub-1 GHz bands.
A CC2538 development platform is sampling to early adopters through the low power RF developer network now. Volume production and sale through authorized distributors is expected in 4Q 2012. The CC1200 will start sampling in late 1Q 2012 with volume production expected in 4Q 2012.
