Energy Harvesting and Energy-Efficient Sensor SolutionsJune 20, 2017 by Paul Shepard
Eta Compute Inc. announced the availability of a new reference design for its revolutionary EtaCore, the world's lowest power microcontroller IP, which operates on the smallest energy harvesting supplies without compromising functionality or performance. In addition, the company announced that its CEO and co-founder Gopal Raghavan, Ph.D., will present on "Energy Harvesting and Energy-Efficient Power Solutions for Sensor Applications" June 27 at 9:00 a.m. at the 2017 Sensors Expo in San Jose. Eta Compute will exhibit in booth #1640.
"Eta Compute is pioneering a revolutionary reduction in power consumption of microcontrollers and SoCs used in the connected world by delivering a 10X improvement in power efficiency over any alternative," said Paul Washkewicz, vice president and co-founder of Eta Compute. "This reference design provides the flexibility and features needed to help accelerate product development and shorten time to market for virtually anyone seeking to capitalize on the explosive IoT market."
The EtaCore ARM Cortex-M3 reference design interfaces to standard Eclipse, Keil and Linux debug and development environments which allows designers to quickly test and customize the functionality and performance of their IoT application. The design consists of sensors for ambient light, temperature, humidity and pressure and is powered by a half-inch square solar cell. Additionally the unit can be networked by on-board LoRaWAN components. The dimensions of the reference design measures 1.5 inches x 3.5 inches.
Eta Compute developed delay insensitive asynchronous logic (DIAL) design IP for maximum power efficiency so that SoCs can be powered by small batteries and energy harvesting. The EtaCore enables reliable voltage scaling down to 0.25 Volts with nanowatts of power consumption. The various energy harvesting techniques, such as solar, thermal, vibration, or RF energy harvesting can supply 15uW to 15mW which is ideal for motion, video, and always-on sensor processing. This Cortex-M3 IP scales power and performance down to the nanowatt arena.
