4Bit Single Chip Microcontroller
DESCRIPTION
FEATURE
The DMC42C2008 is a 4-bit single chip micro-
computer with 8K bytes ROM, and is manufactured
with CMOS silicon gate technology.
Memory Mapped I/O
Program Memory : 8192 x 10 bits
The DMC42C2008 includes peripherals such as 8-bit
Timer/Event Counters, 4-bit A/D Converter, 14-bit
PWM, 8-bit PWM, 6-bit PWM, Watchdog Timer, 4-ch
External Interrupts and OSD controller.
Data Memory
: 512 x 4 bits
Instructions
It provides the hardware features, architectural
enhancements and instructions that are necessary
to make it a powerful and cost effective controller
for applications requiring up to 64K bytes of program-
mable memory.

DMC42P2008
4Bit Single Chip Microcontroller
DMC42P2008
DESCRIPTION
The DMC42P2008 is a system evaluation LSI having a build in One-Time-Programming circuit.
A programming and verification for the internal EPROM is achieved by using a adaptor socket.
The function of this device is exactly same as the DMC42C2008 with programming of internal EPROM.
The DMC42P2008 is the OTP version of the DMC42C2008 with replacement of MASK to EPROM as
as an internal ROM.
