Ember Corp. this week announced the introduction of a product that it is billing as the world’s first ZigBee system-on-a-chip. The EM250 is an 802.15.4-based semiconductor system built to be ZigBee compliant that integrates a programmable microprocessor, RF radio, network protocol stack and memory into a single-chip solution.

The 2.4GHz EM250 is “smaller than a shirt button,” which leads to reduced component size, cost and power consumption for OEMs and system integrators, the company said. In related news, the research firm In-Stat predicted that that market for 802.15.4 nodes and chipsets could grow by 200% from 2004 to 2009, with annual shipments surpassing 150 million units in 2009.
