4Bit Single Chip Microcontroller
DESCRIPTION
DMC42C4008
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.
