DESCRIPTION
The DMC42C4008 is a 4-bit single chip
microcomputer having 8K bytes ROM and is
designed with CMOS silicon gate technology.
The DMC42C4008 includes peripherals such
as various timers, A/D converter(8ch), serial
communication interface(8bit), on-chip oscillator
and clock circuit. It provides the hardware
features, architectural enhancements and
instructions which are necessary to make it
a powerful and cost effective controller for
applications requiring up to 64K bytes of
programmable memory.
