EP7311 Data Sheet
OVERVIEW
The Maverick EP7311 is designed for ultra-low-power
applications such as PDAs, smart cellular phones, and
industrial hand held information appliances. The core-
logic functionality of the device is built around an
ARM720T
processor
with
associativeunified cacheand a writebuffer. Incorporated
into the ARM720T is an enhanced memory management
unit (MMU) which allows for support of sophisticated
operating systems likeLinux
.
