Description

The 4559 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 4559 Group is equipped with two 8-bit timers (each timer has one or two reload registers), a 16-bit timer for clock count, interrupts, and oscillation circuit switch function.

The various microcomputers in the 4559 Group include variations of type as shown in the table below
