SigmaTel's D-Major
TM
audio decoder solutions are ideal for MP3
flash players. SigmaTel's single-chip solution enables companies
to create small MP3 players with a long battery life. SigmaTel
integrates all the essential elements for MP3 flash players: USB
2.0 or 1.1, flash interface, DC-DC converter to enable power for
the entire device, battery recharge, DAC and headphone amp for
music playback, ADC for voice record and MP3 encode, an
interface to LED or LCD, and FM Tuner interface and control.
Besides offering an integrated single-chip solution, SigmaTel also
provides firmware support to operate the device in player mode
and when it is connected to the PC in mass storage mode.
SigmaTel enables MP3 flash players to use the mass storage
drivers included with the Windows and Macintosh operating
systems.
With an integrated DC-DC converter that is controlled through
firmware, SigmaTel's audio decoder solutions are optimized for
lower power consumption. Also, with external circuitry,
SigmaTel-based MP3 flash players can power from USB when
connected to a PC, further conserving battery power
consumption.
SigmaTel audio decoders support MP3 and WMA and are field
upgradeable to enable end users to update their MP3 flash
players to support the latest audio decoders. In addition to MP3
and WMA decode, MP3 encode is supported on analog Line_In,
FM_In, and Mic. WMA Digital Rights Management (DRM) is also
supported for copyright-protected audio content.
