Re: what is AT?

What is the purpose of you having a name? Think of it.

The same for each particular IC in the list of every manufacturer.

Hello
OK C means that you have only one chance to program your MCU and ofcourse that must be your final okayed version of your program but in F series you can erase your MCU thousands of times and reprogram it.
ok?
