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

 

Hello,

I think that this is the smallest:

Thanks for the input but link doesn't leads to the correct page

 

Hello,

As I do not know where you are from, I used the export site, but that will not allow deep links.
Here is the english link:

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.
