STMicrolelectronics' EMIF02-MIC07F3 is a chip that integrates complete noise filtering, ESD protection and biasing. The single IC, measuring 1.37mm?, replaces multiple discrete components that would usually consume at least 20.88 mm?.

EMIF02-MIC07F3 adopts ST's PZT (Lead Zirconium Titanate) process, which allows high capacitance values within ultra-miniature dimensions. It is designed for application in mobile phones and portable media devices as well as in devices featuring voice commands, such as GPS receivers and automotive systems.

Samples of the EMIF02-MIC07F3 are now available. Prices are estimated at $0.25 in quantities of 5,000 units.
