UPD78C10ACW

Product Summary

The UPD78C10ACW 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 UPD78C10ACW is a ROM-less product of the UPD78C11A, and can directly address the external memory up to 64k bytes. The UPD78C10ACW is a product which has more built-in ROM capacity than the mPD78C11A, and its memory (ROM/RAM) can be externally extended up to 56K bytes. The UPD78C10ACW operates at low power consumption, because it has a CMOS construction. Also, it can hold data with low power consumption by using standby function.
