General Description

ADE3700 devices are a family of highly-integrated

display engine ICs, enabling the most advanced,

flexible, and cost-effective system-on-chip solutions

for analog-only input LCD display applications.

The ADE3700 covers the full range of XGA and

SXGA analog-only applications including Smart

Panel designs.

The ADE3700 family is pin-to-pin compatible and

comes in a low-cost, 128-pin LQFP package.

ADE3700 devices use the same software platform

and are backward-compatible with the previous

generation of ADE3xxx Scaling Engines.
