As described by Pike Research, smart meters are the vanguard of Smart Grid deployments, and will represent a $8.4 billion global market by 2015. The opportunity is unprecedented as the industry undergoes a disruptive transition to incorporate new technologies enabling a more efficient, reliable, and bi-directional power distribution and transmission infrastructure.


As the market makes its transition to advanced smart meters, equipment vendors face several challenges. One such challenge is how to support impending Smart Grid communication standards as early as possible. Examples include 802.15.4g, 1901.2, and SEP2.0. Typically, this type of flexibility requires incorporating additionally flexibility in the form of increased processing capability and program storage to handle standard evolutions as well as interoperability. Both items places cost pressure on cost sensitive devices that ship in high volume. A related challenge is in general architecting a product with a 15-20 year replacement cycle the ability to incorporate feature upgrades in the field.


Unfortunately, silicon solutions available today fall short in either providing support for newer technologies or doing so in both a cost effective and scalable manner. Furthermore, these components often only offer very limited scalability, which also constrains field-upgradability. The ASMgrid2 product family reconciles these competing forces through market leading silicon integration and architectural innovation.
