4Bit Single Chip Microcontroller

DESCRIPTION

DMC42C1106

The DMC42C1106 is a 4-bit single chip

microcomputer designed with CMOS silicon

gate technology.

The DMC42C1106 includes such peripherals

as various timers, A/D converter (8ch), serial

communication interface (8bit),LCD Driver

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 program memory.

DMC42P1106

4Bit Single Chip Microcontroller

DMC42P1106

DESCRIPTION

The DMC42P1106 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 DMC42C1106 with programming of the internal

EPROM. The DMC42P1106 is the OTP version

of the DMC42C1106 with replacement of MASK

ROM to EPROM as an internal ROM.
