et4UDESCRIPTION
SheThe DMC42C3008 is a 4-bit single chip microcomputer having
ta8K bytes ROM and is designed with CMOS silicon gate technology.
The DMC42C3008 includes such peripherals as various timers,
aA/D converter, serial communication interface,on-chip oscillator
.Dand clock circuitry. It also comes with high-voltage I/O pins
wthat can directly drive a fluorescent display.
wThe high performance CPU and internal peripherals allow flexible & cost
weffective system design in industrial and home appliances.
