Description

The KS57C0302single-chip CMOS microcontroller has been designed for high performance using Samsung's newest 4-bit CPU core.

With comparator inputs, high-current LED direct-drive pins, serial I/O interface, and a versatile 8-bit timer/counter, the KS57C0302 offers an excellent design solution for a wide range of applications such as mouse controllers, subsystem controllers, and toys.

Up to 15 pins of the 20-pin DIP or 20-pin SOP package can be dedicated to I/O. Pull-up resistors are assignable to all of the pins by software. Four vectored interrupts provide fast response to internal and external events.

In addition, the KS57C0302's advanced CMOS technology provides for very low power consumption and a wide operating voltage range.
