Evaluation kit simplifies design of battery-powered, smart-home products

April 8, 2021 By Aimee Kalnoskas

Aspinity announced the availability of its Acoustic Event Detection Kit (EVK1) for battery-operated, smart home devices that are always listening for acoustic triggers such as window glass breaks, voice, or other acoustic events—delivering the essential technology that helps keep homes and families safe and secure. Featuring the company’s analogML core—a fully analog machine learning processor that promotes system power efficiency by identifying specific acoustic events prior to data digitization—along with Aspinity’s event detection algorithms and Infineon’s new XENSIV IM73A135 high-performance, low-power analog MEMS microphone—the EVK1 is a complete hardware-software kit for the development of small, always-listening smart home devices with extended battery lifetimes.

Traditional acoustic event detection devices are notoriously power-inefficient because they continuously monitor the environment and immediately digitize all microphone data for analysis—even though most of that data are simply noise. A window glass break, for example, may only happen once a decade but the typical glass break sensor uses high-power digital analysis of 100% of the ambient sound data to detect a trigger that rarely (or never) occurs. Aspinity’s EVK1, on the other hand, demonstrates a power-saving alternative. By using an analogML core to detect acoustic events at the start of the signal chain while the microphone data are still analog, the downstream digital system can remain in an ultra-low-power sleep mode until an event is detected. This architectural approach allows designers to build acoustic event detection devices with batteries that last years, instead of months, on a single charge.

The EVK1 features Infineon’s ultra-high performance XENSIV IM73A135 MEMS microphone for accurate, real-time monitoring of acoustic events and reflects another step forward in the ongoing partnership between Aspinity and Infineon Technologies AG. (See: Aspinity and Infineon partner to accelerate development of intelligent sensing products with longer lasting batteries, May 14, 2020.)

Key features

  • AnalogML core—a programmable, analog machine learning processor that uses near-zero-power to detect acoustic or other sensor events in analog sensor data
  • Infineon’s XENSIV™ IM73A135 high-performance analog MEMS microphone—a 73 dB SNR analog MEMS microphone with a power consumption of just 170 μA
  • Aspinity algorithms—easy to load onto analogML core for acoustic detection of window glass break or voice, with additional acoustic event detection algorithms coming soon

Aspinity’s EVK1 is currently sampling to key customers. For more information, email in…@aspinity.com
