UPD78C11A Datasheet 8-bit Single-chip Microcomputer With A/d Converter

Manufacturer: NEC (now Renesas Electronics)

Overview: DATA SHEET DATA SHEET MOS INTEGRATED CIRCUIT µPD78C10A, 78C11A, 78C12A 8-BIT SINGLE-CHIP MICROCOMPUTER (WITH A/D.

This datasheet includes multiple variants, all published together in a single manufacturer document.

General Description

The µPD78C11A 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 µPD78C10A is a ROM-less product of the µPD78C11A, and can directly address the external memory up to 64k bytes.

The µPD78C12A is a product which has more built-in ROM capacity than the µPD78C11A, and its memory (ROM/RAM) can be externally extended up to 56K bytes.
