EP7309 Data Sheet

High-performance,

FEATURES

■ ARM720T Processor

Low-power, System-on-chip

with Enhanced

— ARM7TDMI CPU

— 8 KB of four-way set-associative cache

— MMU with 64-entry TLB

Digital Audio Interface

— Thumb code support enabled

■ Ultra low power

OVERVIEW

— 90 mW at 74 MHz typical

— 30 mW at 18 MHz typical

— 10 mW in the Idle State

The Maverick™ EP7309 is designed for ultra-low-power

applications such as digital music players, internet appliances,

smart cellular phones or any hand-held device that features the

added capability of digital audio decompression. The core-

logic functionality of the device is built around an ARM720T

processor with 8 KB of four-way set-associative unified cache

and a write buffer. Incorporated into the ARM720T is an

enhanced memory management unit (MMU) which allows for

— <1 mW in the Standby State

■ Advanced audio decoder/decompression capability

— Supports bit streams with adaptive bit rates

— Allows for support of multiple audio decompression

algorithms (MP3, WMA, AAC, ADPCM, Audible,

etc.)

support of sophisticated operating systems like Microsoft

Windows CE and Linux .
