ST Microelectronics  is a major supplier of MEMS systems for consumer and portable applications.  

ST has introduced a range of high-performance, low-power stereo microphones that offer superior sound quality and reliability at reduced size and cost.  

ST’s innovative MEMS microphones target existing and emerging audio applications across a range of market segments including cell phones, portable media players, games, digital cameras, security systems, learning devices and hearing aids where factors such as small size, high sound quality, reliability and affordability are critical.  

ST’s MP45DT01 digital-output stereo microphone enables dramatic advancements in sound quality by providing omni-directional sensitivity to detect and filter out background noise.  

Sound quality can be further improved by incorporating multiple microphones in a single audio-input device, especially in noisy environments.  

Such microphone arrays are made possible with the small form factor and the superior characteristics of ST’s MEMS micro-machined microphones.  

Leveraging established high-volume silicon manufacturing processes, MEMS microphones meet price points set by the traditional electret condenser microphones (ECM), while boasting superior reliability and robustness.  

ST’s new microphone uses sensor technology from OMRON that is inherently less susceptible to mechanical vibration, temperature variations and electromagnetic interference.  

ST’s twin advantages of supply chain management and leading-edge MEMS production capacity enable short product development cycles and time-to-volume for high-performance, cost-competitive silicon acoustic devices.  

These advantages will accelerate the growth of the MEMS microphone market by promoting the development of new application areas such as voice-enabled gaming, automotive voice systems, acoustic sensors for industry and security applications as well as medical telemetry.  

According to iSuppli’s research dated September 2009, the market for micro-machined acoustic devices for consumer electronics and mobile handsets is forecast to grow at a CAGR of 18% between 2008 and 2013, when the number of units shipped should exceed one billion parts per year.
