4Bit Single Chip Microcontroller
DMC42C4008
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.

DMC42P4008 DESCRIPTION
The DMC42P4008 is a system evaluation LSI having a built in One-Time Programming circuit. A programming and verification for the internal EPROM is achieved by using a general EPROM programmer with an adapter socket. The function of this device is exactly same as the DMC42C4008 with programming of the internal EPROM. The DMC42P4008 is the OTP version of the DMC42C4008 with replacement of MASK ROM to EPROM as an internal ROM.
