Knowles Corporation introduces the smallest, most efficient digital MEMS microphone on the market with an I²S interface

     Knowles Corporation, the world's leading supplier of micro acoustic solutions and components, announced the introduction of the most advanced integrated circuit built-in audio bus (Inter-IC Sound or I²S) interface MEMS(micro-electro-mechanical System) microphone. It is used in wearable devices, remote controllers, automotive, and smart home automation and security devices.

     Knowles Corporation's solution offers superior size and power consumption, reducing package size by 25% and current consumption by 40% compared to competing products. By using this I²S interface, the microphones with bottom-interface digital MEMS allow manufacturers to connect directly to application processors or microcontrollers, reducing complexity, improving battery performance, and reducing material costs for a more efficient architecture.

     This innovation is particularly important for space-constrained devices such as wearables. The motherboard of a wearable device is very small, so the requirements for the space occupied by its components are very strict. This new technology can be easily integrated with existing mobile device architectures and simplifies system integration by directly connecting to the signal processor.

     "Knowles Corporation is committed to developing advanced audio solutions and a customer-centric strategy to create meaningful technology," Thibault Kassir, Senior Director of Product Management, Mobile Consumer Electronics, said: "This innovation is the first step towards our goal of providing intelligent audio solutions, and it lays a solid foundation for the company's future blueprint."

     "Our expertise in acoustics and audio systems has driven the development of the world's most advanced I²S MEMS microphones," Bertrand Renaud, Product Manager, Mobile Consumer Electronics, said, "The company developed this smart audio solution to meet the growing demand for smaller, more efficient devices, and we are pleased to see that it has been widely used in reference designs for wearable devices. It has been selected by several major consumer electronics customers and shipments will begin in the third quarter."
