KS57C0002/0004
4-BIT CMOS Microcontroller
Product Specification
OVERVIEW
The KS57C0002/0004 single-chip CMOS microcontroller is designed for high-performance using Samsung's
newest 4-bit CPU core. With a four-channel comparator, eight LED direct drive pins, serial I/O interface, and a
versatile
8-bit timer/countkxcellent design solution for a variety of general-purpose applications.
Up to 24 pins of the 30-pin SDIP package can be dedicated to I/O. Five vectored interrupts provide fast response
to internal and external events. In addition, the KS57C0002/0004's advanced CMOS technology ensures low
power consumption and a wide operating voltage range.
