    Thanks for reply.

    I am only interested in ST's ARM based controllers.

    1. USB host and device in single port.

    2. Ethernet

    3. Minimum 4 uart (one multiprocessor communication)

    4. Internal flash and RAM.

    I have gone through STM32F107xx which complete my search. But it give 1.25K byte dedicated SRAM for USB and 4K byte for ethernet. Is it sufficient??

    Other manufacturer gives 16K byte for USB and ethernet each.

    Is ST providing free TCP/IP stack and free USB driver for fast development.

    Use this parametric search :

    1. USB host and device

    Is that both host and device simultaneously (ie, 2 ports), or just 1 port that can be either Host or Device?

    Please suggest me any ARM based controller (STR7, STR9, STM32).

    Do you really mean any ARM based controller, or are you only interested in ST's ARM based controllers?

    Really?! :-?

    You sound remarkably like this guy, who says he prefers NXP or Atmel:

    Have you actually looked at

    http://www.st.com/mcu/familiesdocs-110.html

    ?

    Why do you doubt it?

    Does your application have particularly high data volumes and/or speeds?
