- vidarh 7y agoThey do have some in smaller packages too, e.g. [1] that uses a PLCC-44 package, so ~16.7mm per side instead of ~5.2cm x ~1.5cm. The package above is that big because it's pin-compatible going back to the original 1975 version, and mostly drop-in compatible (barring some issues such as different levels of support for undocumented opcodes). But of course even a PLCC-44 package is big compared to that die.

- joezydeco 7y agoAnd that's kind of my point. If most 6502s are needed as legacy drop-ins, then there's no reason to shrink the die if you're just going to weld it into a massive DIP package.
- vidarh 7y agoYes, I agree with you; sorry if that wasn't clear - absolutely don't think they'd gain much from shrinking it further. Anyone who cares about shrinking it down further would probably gain even more by licensing the core and embedding it together with other functionality anyway.
