Eta Compute and Rohm

Eta Compute and ROHM collaborate on Wi-SUN-compatible sensor nodes

June 25, 2018

Westlake Village, CA, and Santa Clara, CA. Eta Compute Inc., a company focused on delivering next generation autonomous intelligence to mobile and edge devices, and ROHM Semiconductor today announced their collaboration to develop low-power Wireless Smart Ubiquitous Network (Wi-SUN)-compatible sensor nodes. The nodes will combine ROHM’s sensor technology and Eta Compute’s low-power MCUs to deliver low-power solutions for smart utility networks and the IoT.

“Our partnership with ROHM gives our customers access to industry-leading sensor technology combined with the industry’s lowest power microprocessor technology,” said Paul Washkewicz, vice president and cofounder of Eta Compute. “By focusing on Wi-SUN compatibility, we are providing essential components for large-scale outdoor networking required for smart cities and a diverse range of applications in an intelligent loT.”

The nodes coming from the ROHM and Eta Compute partnership will be designed for frequent, low-latency communication that draws less than 1 μA when resting and, more importantly, only 1 mA while sensing. This enables customers to configure devices to sense frequently and still maintain a long life. The nodes will be compatible with Wi-SUN technology, which is based on the IEEE 802.15.4g standard and backed by the Wi-SUN Alliance.

“We are pleased to collaborate with Eta Compute. ROHM has targeted the sensor business as one of our growth strategies. We offer a wide range of sensor line-ups and propose sensor solutions, combining wireless communication devices. By pooling our resources, we will provide customers with the sensor nodes they need to deploy next-generation networks across a wide range of applications,” said Satya Dixit, senior director of solutions marketing at ROHM Semiconductor.

The optimized low power design of EtaCore IP can reduce power consumption by 10X, enabling sensor hubs to perform sensor fusion with local computing and provide real-time data from mobile and IoT-enabled devices. ROHM’s portfolio of sensors that detect environmental/physical conditions and networks for transmitting and sharing sensor data are essential for achieving IoT and for the development and deployment of next-generation sensor networks.

Eta Compute and ROHM will be exhibiting at Sensors Expo 2018 in San Jose at The McEnery Convention Center on June 26-28. Both companies will demonstrate the Energy Harvesting Sensor Evaluation Board using Eta Compute’s low-power MCU based on its proprietary DIAL technology. In addition, Eta Compute will demonstrate ROHM’s BP35C0 Wi-SUN module, BM1383AGLV pressure sensor, BD1020HFV temperature sensor, and BH1792GLC optical heat rate sensor. ROHM will demonstrate its BH1749NUC color sensor.
