DATA SHEET
MOS INTEGRATED CIRCUIT
PD78C17, 78C18
8-BIT SINGLE-CHIP MICROCONTROLLER (WITH A/D CONVERTER)
The
PD78C18 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
PD78C18 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
PD78C17 is the ROM-less version of the
PD78C18. 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.
