To simplify the development of ZigBee wireless connectivity-enabled smart energy infrastructure, home and building automation and intelligent lighting gateways, Texas Instruments announced the availability of the CC2538 system-on-chip (SoC).
Claiming to be the industry’s most integrated ZigBee solution, it packs an ARM Cortex-M3 MCU, memory and hardware accelerators onto one piece of silicon.
The chip supports ZigBee PRO, ZigBee Smart Energy and ZigBee Home Automation and lighting standards to deliver interoperability with existing and future ZigBee products. It also supports IP standards-based development using IEEE 802.15.4 and 6LoWPAN IPv6 networks.
The CC2538 supports smart energy infrastructure applications with scalable memory options from 128 KB to 512 KB Flash, and can sustain a mesh network with hundreds of end nodes via integrated 8 KB to 32 KB RAM options that are pin-for-pin compatible.
The solution enables a secure system while using less energy through AES-128/256, SHA2 integrated hardware encryption engine, optional ECC-128/256, and RSA hardware acceleration engine for secure key exchange. It is optimised for battery-powered applications, consuming only 1,3 μA in sleep mode. The CC2538 supports current and future Z-Stack releases from TI and over-the-air downloads of software for easier upgrades in the field.
The CC2538 development kit (CC2538DK) provides a complete development platform for the CC2538 allowing users to see all functionality without additional layout. It comes with evaluation modules and motherboards with an integrated ARM Cortex-M3 debug probe for software development and peripherals including an LCD, buttons, LEDs, light sensor and accelerometer for creating demo software. The boards are also compatible with TI’s SmartRF Studio for running RF performance tests.
