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 fourway 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® CE and Linux®.
