    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.
