4512 Group
SINGLE-CHIP 4-BIT CMOS MICROCOMPUTER
DESCRIPTION
The 4512 Group is a 4-bit single-chip microcomputer designed with
CMOS technology. Its CPU is that of the 4500 series using a
simple, high-speed instruction set. The computer is equipped with
serial I/O, four 8-bit timers (each timer has a reload register), and
10-bit A-D converter.
The various microcomputers in the 4512 Group include variations
of the built-in memory size as shown in the table below.
