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. Its memory (ROM/RAM) is expandable externally up

to 63 Kbytes.

A detailed explanation of the functions is provided in the user's manual listed below. It should be read before

starting design work.
