Hi,

the smallest AVR with a UART is the S2313 and all bigger ones have at least one UART. All AVRs can be programmed very easy. A programming adapter and the SW you can find at www.lancos.com (ponyprog).

Can you specify your requirements a little bit more?
How much Flash,E²ROM,RAM,speed do you need.

For an USB interface you can use a FT232BM from FTDI. The chip can be conneted to the UART of the AVR.

i am also sugesting At2313 because is the olny mcu from the avr family that will be in produce in next decade


if you want a bigger mcu at8515 is your answer

The at8515 isn't produced anymore. use instead the
mega8515.

Re: AVR uC needed

I thint that an ATmega with Bootloader is a very good option. To program the ATmega for the first time you will need another programmer. As revolt, I suggest you ponyprog and a STK200 or STK300 that you can find at www.lancos.com

For USB conection you can try from Atmel 89C5131. It's not AVR architecture (8051 core) but it's easy to use and program.
