MITSUBISHI MICROCOMPUTERS
4250 Group
SINGLE-CHIP 4-BIT CMOS MICROCOMPUTER
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.
