DESCRIPTION
The 4524 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, serial I/O, four 8-bit timers (each
timer has one or two reload register), 10-bit A-D converter, inter-
rupts, and LCD control circuit.
The various microcomputers in the 4524 Group include variations
of the built-in memory size as shown in the table below.
