By Knowles 110
In response to the growth of smaller, more efficient devices, Knowles developed the most advanced Inter-IC sound, or I²S, interface MEMS microphone for wearables, smartphones, remote controllers, automotive, and smart appliances. Using this I²S interface, the bottom port digital MEMS microphone allows manufacturers to connect directly to application processors or microcontrollers. The result is a more efficient architecture due to decreased complexity, increased battery performance, and a lower cost bill of material. As a result, Knowles’ solution is superior in size and power consumption, with a 25 percent smaller footprint and 50 percent lower current consumption than competitive products. The technology easily integrates with existing mobile device architecture and simplifies system integration through a direct connection to signal processors.
