Canova Tech and ON Semi to Unveil Energy Harvesting Cell Design Platform

April 16, 2013 by Jeff Shepard

Canova Tech Srl and ON Semiconductor will demonstrate a new jointly developed design platform for ultra-low power energy harvesting applications at the Energy Harvesting & Storage Europe conference and exhibition being held in Berlin from April 17-18. Together Canova Tech and ON Semiconductor have developed a fully flexible design platform that enables original equipment manufacturers (OEMs) to test and validate their Energy Harvesting Cell concepts or applications utilizing Canova Tech's ETA Platform harvester module which features ON Semiconductor's LC87F7932B ultra low power, fully programmable microcontroller.

Based on Canova Tech’s IP implemented on silicon, any type of harvesting cell – be it thermo electric, solar, piezo or magnetic – can now power an energy harvesting application with sensor, display and actuator that is software managed by a micro-controller with less than 1 microampere (µA) power consumption. It is proven and ready to use.

The development tool along with all documentation and datasheets are available off-the-shelf to shorten overall development time and enable highly creative concept validation for industry automation, building automation, health care and other applications.

In an autonomous-energy system, especially for Energy Harvesting applications, the collected energy should be consumed as effectively as possible. After the Energy Harvester captures and stores the charge, how to utilize the energy is a key factor as well as how to transform it. The lowest possible power consumption is the most important requirement for device components used for such applications. Microcontrollers play a main role in system tasks, and total power consumption depends upon them. As such, lower power consumption microcontrollers have been required.

ON Semiconductor has introduced an optimally suited microcontroller for Energy Harvesting applications. The LC87F7932B realizes 0.45 µA average power consumption in RTC mode, and 1.5 µA total average power consumption while controlling LCD display, RTC operation, while a 12-bit ADC intermittently operates for temperature measurement.
