Leading the Digital Entertainment Revolution

The EP7312-90 is one of the world's fastest ARM-7 embedded

processors today—with clock speeds of up to 90 MHz, it allows for

real-time MP3 encoding, as well as decoding for all major digital

music standards. The EP7312-90 also supports WMA, MP3, and

AAC playback. With faster than real-time MP3 encoding capability,

the need for a personal computer to create digital audio content is

eliminated. Now, manufacturers can easily build portable rotating

media and flash-based audio players that record and store CD/MP3

data during playback—more than ten hours of music content to be

stored on a single CD-RW disc.

The EP7312-90 delivers high performance with low power,

permitting advanced user interfaces and operating systems in

battery powered entertainment devices. A digital audio interface

(DAI) provides a glueless connection to today's most popular DACs

and ADCs, enabling scalable audio performance and price points. It

also includes our patent-pending MaverickKey™ technology, which

provides consumer Internet product manufacturers with on-chip

security utilizing specific hardware IDs, such as those assigned for

DRM or other authentication mechanisms.

Design in the EP7312-90 for a wide range of consumer

entertainment products, including portable and set-top digital audio

devices, car audio jukebox systems, as well as general-purpose

controller applications.
