    hi there to all

    can anyone recommend me the smallest AVR 8-bit MCU that has a built in uart (the Tx & Rx) ?

    I want it to be DIP ..
    any advice appreciated

    The ATtiny2313A is the first that I can think of. However you can create a software UART on any MCU including the ATtiny13 which is available in an 8-pin DIP.

    The ATtiny4313 is also available and has twice the memory (4K).

    Also, according to the data sheet (Section 15.4.1, page 117) for the ATtiny85, the USI can be set up as a half duplex UART.

    That chips is an 8-pin DIP and has 8K of memory.
