High-Performance,  
Low-Power System on Chip with  
SDRAM and Enhanced Digital  
Audio Interface  
FEATURES  
®
I ARM 720T Processor  
— ARM7TDMI CPU operating at speeds of 74 and 90  
MHz  
— 8 KBytes of four-way set-associative cache  
— MMU with 64-entry TLB  
OVERVIEW  
— Thumb code support enabled  
I Ultra low power  
The Cirrus Logic EP7312 is designed for ultra-low-  
— 90 mW at 74 MHz typical  
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  
— 108 mW at 90 MHz typical  
— <.03 mW in the Standby State  
I Advanced audio decoder/ decompression capability  
— Supports bit streams with adaptive bit rates  
added capability of digital audio compression  
&
decompression. The core-logic functionality of the device  
is built around an ARM720T processor with 8 KBytes 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  
— Allows for support of multiple audio  
decompression algorithms (MP3, WMA, AAC,  
Audible, etc.)
