EP7212

FEATURES

n ARM720T processor

High-Performance, Low-Power

System-on-Chip with LCD

Controller and Digital Audio

Interface (DAI)

— ARM7TDMI CPU

— 8 K-bytes of four-way set-associative cache

— MMU with 64-entry TLB (transition look-aside buffer)

— Write Buffer

— Windows CE enabled

— Thumb code support enabled

OVERVIEW

n Dynamically programmable clock speeds of

18, 36, 49, and 74 MHz at 2.5 V

The EP7212 is designed for ultra-low-power applica-

tions such as organizers / PDAs, two-way pagers,

smart cellular phones or any vertical PDA device that

features the added capability of digital audio decom-

pression. The core-logic functionality of the device is

built around an ARM720T processor with 8 K-bytes 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.

n Performance matching 100-MHz Intel

Pentium-based PC

n Ultra low power

— Designed for applications that require long battery life

while using standard AA/AAA batteries or rechargeable

cells

— Typical Power Numbers

● 90 mW at 74 MHz in the Operating State

● 30 mW at 18 MHz in the Operating State

● 10 mW in the Idle State (clock to the CPU stopped,

everything else running)

● <1 mW in the Standby State (realtime clock ‘on’,

everything else stopped)
