EP7309 Data Sheet
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
Windows
CE and Linux
.
