DESCRIPTION
The 4553 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
two 8-bit timers (each timer has one or two reload register), a 16-bit
timer for clock count, interrupts, and oscillation circuit switch func-
tion.
The various microcomputers in the 4553 Group include variations
of the built-in memory size as shown in the table below.
