They didn't indeed.  The 6510 is a commodore custom IC.

The apple2 and 2plus could be expanded to 64k via a 'language card' in slot
0.  This allowed users to work around the need to have two basic roms handy
by way of loading whichever rom image wasnt on the motherboard into the
extra 16k.

The language card is emulated in hardware on the later apple2's, and is used
to store Apple's ProDOS code during runtime.
