Next-generation technology for market-leading SoundTerminal(TM)
processor/power-amplifier chip supports latest audio processing,
lower amplifier noise, and competitive product design GENEVA, Dec.
21 /PRNewswire-FirstCall/ -- STMicroelectronics (NYSE:STM), the
leading maker of audio chips for flat-panel TVs, today announced
details of its next-generation STA370BWS SoundTerminal(TM) chip,
which delivers increased performance at a highly competitive price.
The new chip employs ST's leading-edge Full Flexible Amplifier
(FFX(TM)) technology to deliver high-quality stereo audio at 10W
and above, in various consumer applications, including the latest
ultra-thin LED-backlit Flat TVs. Advanced chip manufacturing
technologies govern the performance and cost of today's digital
audio chips, delivering advantages that include reduced noise and
distortion, support for more sophisticated audio processing, and
extra features integrated on the chip to reduce the total number of
system components. In addition, each technology evolution delivers
higher functionality per chip size than its predecessor, enabling
extremely competitive pricing relative to performance. The
STA370BWS is the first audio device to use the company's
proprietary BCD8 process technology. An evolution of ST's
successful market-leading BCD6S process, BCD8 is the eighth
generation of ST's Bipolar/CMOS/DMOS technology, which allows the
company to build analog, logic, and high-voltage functions on a
single chip to increase performance and reduce cost. In developing
the STA370BWS, ST has leveraged its BCD8 process to integrate more
sophisticated audio signal processing within the CMOS section,
enabling a better listening experience for end users. The device
also performs a short-circuit check at power on, which increases
application safety and prevents pc-board damage, leading to minimum
rework costs for equipment manufacturers. The device's on-chip
power amplifier also delivers better performance over conventional
digital amplifiers, using ST's FFX technology, which provides
improved audio at the amplifier output. In addition, ST's F3X(TM)
technology, the third-generation of FFX amplifiers, used in the
STA370BWS's auxiliary output, further improves audio quality by
suppressing non-audio signals, such as the carrier waveform that
governs the amplifier's timing, to produce clearer, purer sound
throughout the output-power range. The STA370BWS is the first in a
new generation of ST's SoundTerminal portfolio. The portfolio
currently includes the STA333BW, STA335BW, STA339BW, STA339BWS and
STA369BWS. The new STA370BWS has a resale price of $2.50 for
10,000-piece orders, and is now sampling to lead customers. About
