SD42C/P4404
4Bit Single Chip Microcontroller
Description
The SD42C4404(4302) is a 4-bit single chip micro-computer having 4K(2K) bytes ROM and
is designed with CMOS silicon gate technology. The SD42C4404 includes such peripherals
as various timers, A/D converter, serial communication interface, on-chip oscillator and
clock circuitry. The high performance CPU and internal peripherals allow flexible & cost
effective system design in industrial and home appliances. And the OTP device (42P4404)
can shorten system development periods and help the process for software debugging.

Description
The SD42P4404 is a system evaluation LSI having a built in One-time PROM for
SD42C4404. 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 SD42C4404 by programming to the internal PROM.
The SD42P4404 is OTP version of the SD42C4404 which internal ROM has been changed
from MASK ROM to EPROM.
