DESCRIPTION
The 4554 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
main clock selection function, four 8-bit timers (each timer has one
or two reload register), interrupts, and LCD control circuit.
The various microcomputers in the 4554 Group include variations
of the built-in memory size as shown in the table below.
