et4UDESCRIPTION
SheThe DMC42C4008 is a 4-bit single chip
tamicrocomputer having 8K bytes ROM and is
designed with CMOS silicon gate technology.
aThe DMC42C4008 includes peripherals such
.Das various timers, A/D converter(8ch), serial
wcommunication interface(8bit), on-chip oscillator
w and clock circuit. It provides the hardware
w features, architectural enhancements and
DMC42C4008
instructions which are necessary to make it
a powerful and cost effective controller for
applications requiring up to 64K bytes of
mprogrammable memory.
