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 registers), 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.
