AMI Semiconductor Releases Miniaturized BelaSigna(R) 200 Audio Processing System; New Chipscale Device Optimized for Use in Advanced Small Form Factor Audio Products.

POCATELLO, Idaho -- AMI Semiconductor (Nasdaq:AMIS), a designer and manufacturer of state-of-the-art integrated mixed-signal and structured digital products, today announced the availability of a new miniaturized version of its BelaSigna 200 audio processing chip, optimizing the technology for use in advanced, small form factor precision audio products for the consumer and industrial markets.

The product has been developed based on a new miniature chipscale package (CSP) measuring 3.8 x 2.4mm, approximately one-seventh the size of the previously available QFN package. BelaSigna 200 interfaces seamlessly with wireless technology including Bluetooth(R) subsystems and consumes only a few mA of current at 1.8V. It contains a DSP core, stereo CODEC, memory, power management, and a highly efficient, hardware-based WOLA filterbank coprocessor, which greatly reduces power consumption and chip size while providing low group delay and adjustable parameters for easy integration into a wide range of designs.

"We have witnessed good success with BelaSigna 200 since its market introduction. It is the most complete, lowest power and smallest programmable audio processing system available, which also offers the flexibility of a generic DSP system at the size and power consumption of a dedicated ASIC," said David Coode, manager of AMI Semiconductor's audio group. "The new miniaturized version enables our customers to design BelaSigna 200 into even smaller products."

Currently, BelaSigna 200 is targeted for use in small form factor, precision digital speech- and audio-centric products such as wireless headsets and headphones. These popular devices continue to shrink in size to become more discreet and comfortable to wear.
