The question is whether we really want to do anything for them (except for the ATmega32U6, of course). As far as I understand, all the "A" parts are metal shrink devices which are not supposed to cause any end-user visible change. All the registers are the same, the device signature is the same as for the corresponding non-A device. From a toolchain's point of view, they are completely identical to the non-A parts, asking for separate toolchain support would be the same as asking for separate toolchain support for e.g. an ATtiny13V, or an ATmega128L which we never considered. The only user-visible change is in fact that the distinction between high-frequency (no specific suffix) and low-voltage (suffices L or V) does no longer exist since the smaller dies are guaranteed to handle both ends of the scale within a single part. The only suffix letter which caused us to start separate support for "suffix" devices was the "P", because in cases where both, the picopower and the non-picopower part do exist, they are indeed different parts, with different registers, and a different signature. I always considered that a somewhat unfortunate decision but we just had to live with it. -- cheers, J"org .-.-. --... ...-- -.. .
