Manufacturers seeking an audio microprocessor that
supports Microsoft's PlaysForSure(TM) 2.0 and PlaysFromDevice
specifications now have a compelling new choice with the ColdFire(R)
MCF5251 from Freescale Semiconductor (NYSE:FSL) (NYSE:FSL.B).
The MCF5251 audio processor is an excellent choice for portable
and in-car infotainment audio applications such as satellite radio, CD
or hard disk drive (HDD) compressed audio players, USB Thumb drive
players, jukeboxes and MP3 docking stations. Additionally, the MCF5251
enables hours of audio playback time and enough power to drive MPEG4
QCIF video playback.
"Our latest generation of ColdFire audio processors offers an
impressive list of multimedia features enabling OEMs to bring exciting
new possibilities to their latest automotive and consumer device
projects," said Berardino Baratta, general manager of the Multimedia
Applications Division for Freescale. "Combined with our comprehensive
software and Microsoft PlaysForSure and PlaysFromDevice support, this
highly integrated processor reduces chip count and allows designers to
create even smaller form factor audio devices."
The ColdFire MCF5251 supports Microsoft's PlaysForSure 2.0 and
PlaysFromDevice specifications for security and portability. These
technologies allow consumers to connect their MP3 player via USB to
the car audio system, play back music over the car audio system and
have full access to the device contents via the in-car controls.
"Based on the performance we see on the ColdFire MCF5251
processor, we are confident that the HDD and CD reference software
solutions we are building will be the best in the market for both car
audio and portable HDD players," said Mr. K. Srinivasan, CEO of AllGo
Embedded Systems, Bangalore, India. "Our free PlaysForSure V2.0
compliant software package will help existing and new Freescale
customers designing with the MCF5251 to adopt the new Microsoft
standard seamlessly, thus, accelerating their time to market."
ColdFire MCF5251
The MCF5251 is powered by the ColdFire V2 32-bit microprocessor
core with a small DSP engine (eMAC) that is well suited for MP3 and
similar applications. With two automotive CAN interface modules in the
same device, the MCF5251 works as a digital audio solution for car and
portable audio applications. Other hardware features include on-chip
USB 2.0 On-the-Go (OTG) technology with an integrated high-speed (up
to the specification maximum of 480 Mbps) transceiver and a
tamper-proof real-time clock for improved digital rights management
(DRM). A high-speed UDMA ATA interface facilitates fast data transfers
for easy uploads and downloads. Additionally, the MCF5251 is
AECQ100-qualified, a mandate by the automotive industry for compressed
audio.
The scalable MCF5251 software requires minimal hardware
dedication, which can shorten design cycles and makes it easier to
react to changing market requirements. Software compatibility with the
SCF5249 and SCF5250 devices enables a simple migration path for
next-generation devices. Also, the MCF5251 comes with a comprehensive
audio reference software package that supports a wide range of audio
encode, decode and DRM standards.
Microsoft Digital Rights Management
Freescale has adopted Microsoft's Windows Media Audio Digital
Rights Management 10 (WMA-DRM10) format for its MCF5251 components and
development tools. DRM is an important way to protect the ownership of
subscription-based content, such as downloaded music, even as it
passes from one portable device to another. Many content providers are
now supporting WMA-DRM10, and Freescale incorporates these
technologies into its ColdFire product family.
Availability
To get next-generation designs to market more quickly, Freescale
provides schematics, layout files and component lists for a 1.8-inch,
20 GB HDD reference design that includes a color liquid crystal
display and support for JPEG, MPEG4 and USB 2.0 OTG. The MCF5251 is
available now in production quantities. Visit
