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
