STMicroelectronics : STMicroelectronics and Soundchip Introduce Components to
          Create Smart High-Definition Audio Accessories That Dazzle

  Powerful new audio engines combined with high-performance MEMS microphones
enable feature-rich, software-controlled headsets that take personal audio to
                                the next level

Geneva, Switzerland, February 20, 2013 - STMicroelectronics (NYSE: STM), a
global semiconductor leader serving customers across the spectrum of
electronics applications and a leading supplier of high-performance audio ICs,
together with Soundchip, a Swiss-based innovator in audio-systems technology
and originator of the High-Definition-Personal-Audio(TM) (HD-PA^®) Reference,
today introduced two HD-PA audio engines, STANC0 and STANC1, and an HD-PA
microphone, the MP34AB01H, which enable the creation of exciting, feature
rich, software-controlled smart audio accessories.

STANC0 and STANC1 are HD-PA audio engines designed to regulate the sound
performance of over-ear, on-ear and in-ear headsets. Designed for stereo and
monaural applications respectively, STANC0 and STANC1 incorporate Soundchip's
patented Soundcore R3(TM) electronics, which implement a patented hybrid
analog-digital architecture that is capable of processing sound at
zero-latency with an unmatched 100 dB of dynamic range.

STANC0 and STANC1 incorporate the means to deploy powerful digitally
configurable feedback and feed-forward active noise cancellation (ANC)
processing for the removal of unwanted environmental noise, as well as
digitally controlled binaural monitoring to provide natural, open ear
listening with comfortable, occlusion-free speech.

Unlike competitor's products, which configure active noise cancelling filters
through the selection and placement of hundreds of passive components around a
"noise cancelling" op-amp, STANC0 and STANC1 integrate these filters on-chip.
Filter and device settings may be programmed digitally to optimize their
performance with connected acoustics or configured in real-time by a
complementary DSP, such as the STM32 F4, to enable exciting new features such
as auto-active noise cancellation and augmented reality.

STANC0 and STANC1 are highly integrated devices supplied in a compact 4.5mm x
4.5mm LF-BGA package. Both devices can operate from a single AAA battery or
host-supplied power source ensuring their suitability for the wired and
wireless aftermarket, as well as in-box audio accessories.

Mark Donaldson, Soundchip CEO, said, "The latest HD-PA devices from
STMicroelectronics present exciting new opportunities for customers to extend
boundaries of innovation in personal audio and to realize a new generation of
superior-sounding active noise-cancellation headsets and smart audio

"As a global leader in the design and high-volume manufacturing of integrated
circuits and MEMS, ST's collaboration with Soundchip and the introduction of
these new HD-PA components provide a tangible demonstration of our commitment
to audio and smart audio in particular," said Andrea Onetti, Audio and Sound
Business Unit Leader at STMicroelectronics.

The MP34AB01 is a compact 3.76mm x 2.95mm analog, bottom-port, HD-PA-compliant
MEMS silicon microphone designed specifically for combination with
STMicroelectronics' HD-PA audio engines. Featuring a flat audio response
between 20Hz and 20kHz, market-leading 66dB SNR, zero-latency output, and
surface-mount assembly, the MP34AB01H is the perfect companion to STANC0 and
STANC1, providing an accurate and reliable measure of in-ear and ambient sound
conditions necessary for the effective operation of feedback and feed-forward
active noise cancelling.

HD-PA components are supported by a comprehensive suite of Soundstation(TM)
computer-aided-design and manufacturing tools, which simplify product
development and significantly improve manufacturing reliability. Component
samples and evaluation boards are available to customers under a dedicated
non-disclosure agreement.

About HD-PA:
Consumers are adopting mobile entertainment, communications and gaming devices
in ever increasing numbers with each new generation of device offering
substantially improved power and performance. An aspect of end product that
has remained relatively unchallenged during this period of growth is audio and
in particular personal audio or audio delivered at the ear. As consumers
search for a better sound experience on-the-go, an opportunity has emerged to
demonstrate leadership in audio systems engineering and electroacoustics
through intelligent innovation.

The High Definition Personal Audio(TM) reference has been developed to
encourage a step change in the performance and capabilities of personal audio
devices. This change is achieved by applying innovative audio system
technologies in concert with state-of-the-art processing and sensory silicon,
including MEMS. Devices that comply with the HD-PA^® reference meet an
ambitious standard of performance and offer their users enhanced sound
quality, comfort and convenience in a manner that is resilient to
environmental factors, including noise.
