The Motorola MC68012 processor is a 16/32-bit microprocessor from the early 1980s. It is an 84-pin PGA[1] version of the Motorola MC68010. The memory space was extended to 2GB (causing the same issue as the 68020 for any programs using the high byte of an address except those only using the high bit) and an RMC pin was added, in order to help the design of multiprocessor systems with virtual memory[2][3]. All other features of the MC68010 were preserved.
