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 -- (Marketwire) -- 02/20/13 --  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(R)) 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 accessories." 
"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(R) 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.
