EP7311 Data Sheet  
High-Performance,  
FEATURES  
I ARM720T Processor  
Low-Power System on Chip with  
SDRAM and Enhanced Digital  
Audio Interface  
— ARM7TDMI CPU  
— 8 KB of four-way set-associative cache  
— MMU with 64-entry TLB  
— Thumb code support enabled  
I Ultra low power  
OVERVIEW  
— 90 mW at 74 MHz typical  
— 30 mW at 18 MHz typical  
— 10 mW in the Idle State  
— <1 mW in the Standby State  
I 48 KB of on-chip SRAM  
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 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  
I MaverickKey IDs  
— 32-bit unique ID can be used for SDMI compliance  
— 128-bit random ID  
®
operating systems like Linux .  
I Dynamically programmable clock speeds of  
18, 36, 49, and 74 MHz
