Texas Instruments Inc. (TI) has churned out the CC2538 SoC that according to the company simplifies the development of ZigBee wireless connectivity-enabled smart energy infrastructure, home and building automation and intelligent lighting gateways. The device is touted as a cost-efficient ARM Cortex-M3 MCU that features memory and hardware accelerators on one piece of silicon, indicated the firm.

The CC2538 supports ZigBee PRO, ZigBee Smart Energy and ZigBee Home Automation and lighting standards to deliver interoperability with existing and future ZigBee products. The SoC also supports IP standards-based development using IEEE 802.15.4 and 6LoWPAN IPv6 networks for maximum flexibility.

The device supports smart energy infrastructure applications with scalable memory options from 128-512K flash and can sustain a mesh network with hundreds of end nodes via integrated 8-32K RAM options that are pin-for-pin compatible for maximum flexibility.

The CC2538 enables a secure, fast bring-up a 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 also optimized for battery-powered applications using only 1.3uA in sleep mode. It has a temperature operation range up to 125°C and supports fast digital management—no interfaces are required externally or between system-on-chip components.

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 high-performance CC2538 evaluation modules (CC2538EMK) and mother boards 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.

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 comes in an 8 x 8mm QFN56 package and is available through authorised distributors for under Rs.163.04 ($3) in high volumes. The CC2538 is also available through TI’s free sample programme.

The CC2538DK costs Rs.16,250.00 ($299) and can be ordered on TI’s eStore.
