Hello all,

I am looking for an ARM processor with integrated Ethernet MAC and 
keypad interface & CMOS interface.

Appreciate any suggetsions.

I suggest you start looking at data sheets. There are lots of processors these days with built-in Ethernet, there are no standards that I know of for a 'keypad interface' so that phrase is probably meaningless, and "CMOS interface" _is_ meaningless. -- Tim Wescott Control systems and communications consulting http://www.wescottdesign.com Need to learn how to apply control theory in your embedded system?

i know lots of processor with built-in ethernet(MAC).
But these processor does not have CMOS Image Sensor interface and keypad 
interface same times...
so i'm looking for processor which has above three functions(ethernet, 
CMOS image sensor and keypad i/f)

i found freescale i.mx27...

Your initial post did not say "image sensor". Any MCU with spare I/O pins can scan a keypad. You don't need a special circuit. This can be done in software using less than 1% of the CPU processing time. I'm glad you found something that will work for you. Be sure the Freescale part is right for your needs in other respects as well.
