High-Performance,
Low-Power System on Chip with
SDRAM and Enhanced Digital
Audio Interface
EP7312 Data Sheet
OVERVIEW
The Cirrus Logic
EP7312 is designed for ultra-low-
power portable and line-powered applications such as
portable consumer entertainment devices, home and car
audio juke box systems, and general purpose industrial
control applications, or any device that features the
added
capability
of
digital
decompression. Thecore-logic functionality of thedevice
is built around an ARM720T processor with 8 KBytes of
four-way set-associativeunified cacheand a writebuffer.
Incorporated into the ARM720T is an enhanced memory
management unit (MMU) which allows for support of
sophisticated
operating
Windows
CE and Linux
.
