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.

DMC42P3008 DESCRIPTION
The DMC42P3008 is a system evaluation LSI having a built in One-time PROM for DMC42C3008. A programming and verification for the internal PROM is achieved by using a general EPROM programmer with an adapter socket. The function of this device is exactly same as the DMC42C3008 by programming to the internal PROM. The DMC42P3008 is OTP version of the DMC42C3008 whose internal ROM has been changed from MASK ROM to EPROM. * CAUTION : P3008 does not include internal pull-down resistor for high voltage output, so user has to connect externally.
