Ember® ZigBee® ICs target the Internet of Things

November 07, 2012 // By Jean-Pierre Joosting
Silicon Laboratories has announced the addition of Ember® ZigBee® solutions to its portfolio of low-power wireless embedded devices for the Internet of Things (IoT).

Available now through Silicon Labs' global distribution channel, the EM35x system-on-chip (SoC) and network co-processor (NCP) products and EmberZNet PRO software enable designers to develop high-performance, low-power and reliable 2.4 GHz wireless mesh networking solutions for smart energy, home automation, security, lighting, and other monitoring and control applications for the rapidly growing IoT market.

Industry experts predict that the number of connected devices for the IoT will surpass 15 billion nodes by 2015 and reach 50 billion nodes by 2020. By adding Ember ZigBee solutions to its portfolio of sub-GHz wireless ICs, wireless microcontrollers (MCUs), and 8- and 32-bit mixed-signal MCUs, the company is uniquely positioned to provide the wireless connectivity and low-power processing platforms for many of the connected devices that enable the IoT.

The Ember ZigBee platform is the most integrated, comprehensive and feature-rich ZigBee solution available for 2.4 GHz wireless networks, delivering unmatched wireless performance, low power consumption and code density in a compact package. The most widely used ZigBee platform for mesh networking applications, EM35x devices can be deployed as SoCs for cost-sensitive, low-power sensor networks and other simple connected devices or configured as NCPs for complex applications running on high-performance applications processors. The EM35x devices integrate a 2.4 GHz IEEE 802.15.4 transceiver with an +8 dBm power amplifier, ARM Cortex-M3 core, up to 192 kB flash memory and 12 kB RAM. The Ember ZigBee devices offer superior message latency and data throughput and at least 25 percent longer battery life than any other ZigBee solution.

EM35x devices are tightly integrated with the field-proven EmberZNet PRO mesh networking protocol stack, which sets the bar for ZigBee stack reliability. Deployed in more wireless networking products than any other ZigBee stack, EmberZNet PRO software provides enhancements for robustness, scalability and ease-of-use even in larger networks and more challenging environments. The software stack is complemented by the proven Ember Desktop environment, which reduces design time by providing sophisticated visualization
