High-performance,  
FEATURES  
ARM720T Processor  
Low-power, System-on-chip  
with SDRAM & Enhanced  
Digital Audio Interface  
— ARM7TDMI CPU  
— 8 KB of four-way set-associative cache  
— MMU with 64-entry TLB  
— Thumb code support enabled  
Ultra low power  
OVERVIEW  
— 90 mW at 74 MHz typical  
— 30 mW at 18 MHz typical  
— 10 mW in the Idle State

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  
MaverickKey IDs  
®
support of sophisticated operating systems like Linux .  
— 32-bit unique ID can be used for SDMI compliance  
— 128-bit random ID  
Dynamically programmable clock speeds of  
18, 36, 49, and 74 MHz
