Motorola 68012
The processor Motorola 68012 is a Microprocesseur CISC 16/32 bits of the m68k family of Motorola.
The 68012 was manufactured in the middle of the years 1980. It is very similar to the Motorola 68010 except its a little particular adress bus on 31bits: Indeed this one has signals A0-A29 and A31; a30 signal is replaced by the signal RMC, credit when the TestAndSet instruction is carried out, which limits its capacity of addressing to 2 X 1 Gigabytes.
The 68012 were never very popular, the additional cost induced by case PGA84 not returning it interesting in practice. The manufacturers data processing passed directly to the Motorola 68020 for the evolution of their hardware.
