Can someone shed some light on ATMELS nomenclature in naming their devices. For example what is the difference between an ATMEGA324P and an ATMEGA328A or -PA.
So far I can only figure out that the 32 in it's name means 32K of flash.
I have been looking for some sort of a key, an explanation of what the extra digits and letters in the name mean, but could not find anything like that on ATMELS website.
