4Bit Single Chip Microcontroller
DMC42C3008
DESCRIPTION
The DMC42C3008 is a 4-bit single chip microcomputer having
8K bytes ROM and is designed with CMOS silicon gate technology.
The DMC42C3008 includes such peripherals as various timers,
A/D converter, serial communication interface,on-chip oscillator
and clock circuitry. It also comes with high-voltage I/O pins
that can directly drive a fluorescent display.
The high performance CPU and internal peripherals allow flexible & cost
effective system design in industrial and home appliances.
AND the OTP device (42P3008) can shorten system development periods
and help the process for software debugging.
