Designers of smart meters can now reduce time to market, raise the bar for higher accuracy, and secure their designs with Capistrano, a smart grid reference platform from Maxim Integrated Products. Powered by the company’s Zeus metering SoC, Capistrano protects designs with advanced cryptography, physical attack detection, and life-cycle security schemes. Protecting more than just the smart meter, the security technology is capable of securing any distributed node in the smart grid. Additionally, the high integration in Capistrano makes it versatile—it simplifies smart grid designs by integrating four complex processors: an applications processor, metering microcontroller, metering front-end/DSP, and security coprocessor. It also offers the best accuracy in the industry — 0.1% over a wide current range of 8000:1. The combination of advanced measurement, powerful security tools, and efficient processing allows Capistrano to support evolving application design requirements. Thus it is ideal for a wide variety of applications, including smart meters, smart lighting, solar inverters, building automation, submetering, and other smart applications.
