public key binary signing
Clawson, RSA on the AVR can be done As it is a much better processor then you think :lol: , And it only uses 690 Bytes, Depending on how you will construct your bootloader it can...

Mass producing / Mass programming
Normally you will give the binary file or ELF file that also has the fuse setting in it for programming. But if you do not trust your manufacture then go some ware else. As you...

AVR Microcontroller with 2+ RS232 lines
You can also make a software uart if your baudrate is not to hi. but 9600 baud you can do, and that is including 8 times over sampling (interrupt every 13 uS or every 208...
