The standard version of the EOS S3 already features low power consumption, but the LV version reduces power by an additional 33% for a longer battery life. For example, power consumption for a typical always-listening daily use case can now be less than 300µW. 

Both the standard EOS S3 and the new EOS S3 LV are pin compatible, which enables designs developed for the standard device to be easily migrated to the new LV device. Both versions are fully software and design-file compatible and support the Sensory TrulyHandsfree wake-word technology, further facilitating design migration. The device uses an ARM Cortex M4F core with algorithms implented on the Quicklogic FPGA fabric to support sensor applications in smartphones, wearables, hearables and IoT devices,

“The EOS S3 voice and sensor processing platform has always featured industry-leading ultra-low power consumption,” said Brian Faith, CEo and president of QuickLogic. “We continue to aggressively reduce power consumption so that our customers can continue to deliver new and exciting products with extended battery life.”

A reference design for a wireless voice control system combines the EOS S3 with Nordic’s nRF51822 multiprotocol Bluetooth Low Energy (BLE) SoC. The reference design is the first commercially available product to support voice-over- Bluetooth LE connectivity with Amazon Alexa and consumes only 640µW for always-on listening and ”Alexa” wake-word detection. The LV version dropped into the design reduces this even further.

The EOS S3 LV voice and sensor processing SoC and its associated development tools, IP and reference designs are available now.
