DESCRIPTION

The 4250 Group is a 4-bit single-chip microcomputer designed with CMOS technology. Its CPU is that of the 720 series using a simple instruction set. The computer is equipped with one 8-bit timer which has a reload register and the interrupt function. The various microcomputers in the 4250 Group include variations of the built-in memory type as shown in the table below.
