The 78C12A is a CMOS 8-bit microprocessor which can integrate 16-bit ALU, ROM, RAM, an A/D converter, a multi-function timer/event counter, and a general-purpose serial interface into a single chip, then expand the memory (ROM/RAM) up to 60K bytes externally. The mPD78C10A is a ROM-less product of the mPD78C11A, and can directly address the external memory up to 64k bytes. The 78C12A is a product which has more built-in ROM capacity than the PD78C11A, and its memory (ROM/RAM) can be externally extended up to 56K bytes. The 78C12A , mPD78C11A, and PD78C12A operated at low power consumption, because they have a CMOS construction. Also, they can hold data with low power consumption by using standby function.
On-chip PROM products, 78C12A which are ideal for evaluation or preproduction use during system development, early start-up and short-run multiple-device production of application sets, are available.
