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.
