TDK Corporation (TSE:6762) announces that its low-power InvenSense T5838 and T5837 digital PDM microphones, part of the SmartSound™ family, have established themselves as the microphone of choice for low-power edge AI application processors that perform keyword detection, due to its innovative Acoustic Activity Detect (AAD) feature that enables system power savings, thus prolonging battery life, and ability to intelligently detect keywords or voice commands. With their exceptional power efficiency and superb performance, offering 68 dBA SNR and consuming only 130 µA in always-on mode and 330 µA in high-performance mode, the T5838 and T5837 microphones enable developers to integrate voice command functionalities and audio detection capabilities into their products.
Key features and advantages of the T5838 and T5837 microphones for low-power edge AI applications include:
“The low power consumption and AAD functionalities of the T5838 microphone are essential to our customers’ who are deploying energy-efficient, high-performance edge AI solutions in speech recognition and acoustic event detection,” stated Kurt Busch, Syntiant’s CEO. He further emphasized, “Syntiant has closely collaborated with TDK to maximize the use of the T5838’s AAD features with our Neural Decision Processors, aiming to deliver the most power-efficient solutions available in the market today.”
“RASynBoard is a tiny, ultra-low power, edge AI/ML board that achieves highly efficient processing of acoustic- and motion events,” stated Jim Beneke, VP, Advanced Applications Group, Avnet. “TDK’s innovative SmartSound performance solutions continue to represent disruptive and ground-breaking products that improve end user experience, empowering our customers and partners.”
“The combination of Syntiant’s NDP120 neural processor and our T5838 digital PDM microphone enables always-on speech recognition and audio detection capabilities for edge IoT applications,” said Uday Mudoi, VP & GM – Microphone BU, InvenSense, a TDK group company. “The Avnet RASynBoard Kit with TDK’s T5838 Microphone and ICM-4670 IMU will accelerate time to market for customers building smart edge systems.”
TDK’s T5838 and T5837 are available now for evaluation and integration into various devices. For more information or to request a sample, please visit https://invensense.tdk.com/smartsound/ or contact InvenSense Sales at inv.sales.us@tdk.com.
TDK will be demonstrating the T5838 and T5837 microphones at the upcoming Sensors Converge 2023, booth #992 at the Santa Clara Convention Center, June 20-23, 2023. TDK will present a full range of sensor system solutions targeted for applications across automotive, consumer, health, industrial, machine learning, robotics, and more across multiple TDK product brands: InvenSense, Micronas, Qeexo, and Trusted Positioning.
