EP7309 Data Sheet  
FEATURES  
I ARM720T Processor  
High-Performance,  
Low-Power System on Chip  
Enhanced  
— ARM7TDMI CPU  
— 8 KB of four-way set-associative cache  
— MMU with 64-entry TLB  
Digital Audio Interface  
— Thumb code support enabled  
I Ultra low power  
OVERVIEW  
— 90 mW at 74 MHz typical  
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 systems like Microsoft®  
Windows® CE and Linux®.  
— 30 mW at 18 MHz typical  
— 10 mW in the Idle State  
— <1 mW in the Standby State  
I Advanced audio decoder/decompression capability  
— Supports bit streams with adaptive bit rates  
— Allows for support of multiple audio  
decompression algorithms (MP3, WMA, AAC,  
ADPCM, Audible, etc.)
