OVERVIEW

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

support of sophisticated operating systems like Microsoft

Windows
