Overview

DATA SHEET MOS INTEGRATED CIRCUIT µ PD78C17, 78C18 8-BIT SINGLE-CHIP MICROCONTROLLER (WITH A/D CONVERTER) The µPD78C18 is an 8-bit CMOS microcontroller which integrates 16-bit ALU, ROM, RAM, an A/D converter, a multi-function timer/event counter, and a general-purpose serial interface onto a single chip, and whose memory (ROM/RAM) is externally expandable up to 31 Kbytes.

The µPD78C18 can operate at low power consumption because of its CMOS architecure and is provided with a standby function that enables data retention with an even lower power consumption.

The µPD78C17 is the ROM-less version of the µPD78C18.

Key Features

  • 159 types of instructions: 87AD series instruction set plus multiply/divide and 16-bit operation instructions Instruction cycle: 0.8 µs (at 15-MHz operation) Internal ROM: 32768 x 8 bits (µPD78C18 only) Internal RAM: 1024 x 8 bits Up to 64 Kbytes of memory (ROM/RAM) can be directly addressed. High-resolution 8-bit A/D converter: 8 analog inputs General-purpose serial interface: Asynchronous, synchronous, I/O interfac.
