Looking for ARM with Ethernet MAC+ Keypad interface + CMOS interface....

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.

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)

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.
