Abstract: An integrated MEMS acoustic sensor has a MEMS transducer and a programmable electronic interface. The programmable electronic interface includes non-volatile memory and is coupled to the MEMS transducer. Using programmable electrical functions, the programmable electronic interface is operable to sense variations in the MEMS transducer caused by application of an acoustic pressure to the MEMS transducer.
