EP7211

Preliminary Data Sheet

FEATURES

High-Performance Ultra-Low-

Power System-on-Chip with

LCD Controller

I Dynamically programmable clock speeds of

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

I Performance matching 100-MHz Intel^

Pentium-based PC

I Socket and register compatible with CL-PS7111

I Ultra low power

OVERVIEW

— Designed for applications that require long battery life

while using standard AA/AAA batteries or rechargeable

cells

— 170 mW at 74 MHz in the Operating State

— 50 mW at 18 MHz in the Operating State

— 15 mW in the Idle State (clock to the CPU stopped,

everything else running)

— 10 µW in the Standby State (realtime clock ‘on’,

everything else stopped)

The EP7211 is designed for ultra-low-power applica-

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

smart cellular phones, and industrial hand-held infor-

mation appliances. The core-logic functionality of the

device is built around an ARM720T processor with 8

kbytes 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 Microsoft Windows CE support.

I LCD controller

— Interfaces directly to a single-scan panel monochrome

LCD

— Panel width size is programmable from 32 to 1024 pixels

in 16-pixel increments

The EP7211 also includes a 32-bit Y2K-compliant

Real Time Clock (RTC) and comparator.

— Video frame buffer size programmable up to 128 kbytes

— Bits per pixel programmable from 1, 2, or 4

(cont.)
