FM1188 Voice ProcessorProduct Brief

FM1188 is a low power voice processor for portable

hands-free applications. With SAM technology, it

delivers improved noise suppression for bothstationary noise and non-stationary noise with better

voice quality and superior full duplex capability.

Consuming less than 35mW, FM1188 is ideal for

any portable application with stringent requirements

for battery life and power consumption. Offered in a

small 5x5mm BGA package or a 7x7mm LQFP

package option, FM1188 is ideally suited for

applications including portable hands-free car kits

(HFCK), PNDs, smartbooks and VoIP phones.

To achieve the lowest possible power consumption,

FM1188 features an integrated hardware acceleratorto speed up voice related applications. This new

device is designed to achieve the lowest power while

providing the highest performance. With an

enhanced CODEC, FM1188 provides high SNR for

the best voice quality. FM1188 provides excellent

noise suppression and full duplex capabilities,

including non-linear echo cancellation and side tone

cancellation.

For Bluetooth applications, the FM1188 provides a

serial port interface that supports all formats.

FM1188 is pin compatible with FM1182E but lacksUSB support.

ApplicationsTarget applications for FM1188 are

Hands-free car kit PND and GPS phones VoIP handset and speakerphone. Automotive
