Freescale Semiconductor and Cirrus Logic reveal a reference design that combines Cirrus Logic's CS5463 analogue front end (AFE) chip with Freescale's 8bit AC60 MCUs to address the growing digital utility meter market. The reference design offers smart meter OEMs a solution that increases performance and design flexibility while lowering system costs.

Smart power meters provide an economical way to measure energy use in residential settings, and to provide real-time pricing based on demand so that energy consumption can be minimised during peak periods.

According to Berg Insight, worldwide deployment of smart electricity meters will reach 30.25 crore at the end of 2015, based on a compound annual growth rate of 31.1 per cent between 2009 and 2015. In the next five years, penetration rates for smart meter technology are projected to more than double to nearly 50 per cent in Europe and North America, while Asia Pacific is projected to reach 25 per cent by 2015, from less than one per cent today. Growth will continue into the second half of this decade, with many markets approaching 100 per cent penetration by 2020.

Key market drivers include global efforts to upgrade the electric grid, such as the United States' Rs.2.01 lakh crore ($43 billion) energy sector stimulus package that includes Rs.21,013.21 crore ($4.5 billion) for intelligent grid projects like advanced metering infrastructure.

Cirrus Logic's CS546X family claims best-in-class energy measurement accuracy for next-generation smart grid devices. As power quality and grid efficiency efforts gain momentum, Cirrus Logic energy measurement chips benefit utility industry customers by generating the high-quality energy measurement data needed to deliver on-demand energy usage information accurately.

The Freescale Kinetis portfolio of MCUs gives OEMs the flexibility to choose among a variety of MCUs that are suited for their system. Freescale's MQX RTOS and algorithms run on a dedicated DSP and are programmable to run on the MCU. Freescale and Cirrus Logic plan additional single-phase meter reference designs in the future that feature new AFE and MCU products.
