General description:

SN9C2028AF is designed for low cost dual mode CMOS camera solution.

It highly integrated single chip solution that included CMOS sensor interface, SDRAM interface, USB interface, compression engine, LCD driver, embedded 16bit DSP and low battery detection function.

This dual mode camera solution is not only for DSC function but also with the live video mode when attached to PC.

SN9C2028AF provide a solution that can makes balance both in performance and price and most flexible in function for customers design their own style.
