OVERVIEW
FEATURES
ARM720T processor
— 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
Dynamically programmable clock speeds of
18, 36, 49, and 74 MHz at 2.5 V
Performance matching 100-MHz Intel
Pentium-based PC
Ultra low power
— Designed for applications that require long battery life
while using standard AA/AAA batteries or rechargeable
cells
— Typical Power Numbers
G
90 mW at 74 MHz in the Operating State
G
30 mW at 18 MHz in the Operating State
G
10 mW in the Idle State (clock to the CPU stopped,
everything else running)
G
<1 mW in the Standby State (realtime clock ‘on’,
everything else stopped)
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.
