KS57C0301/0302 MICROCONTOLLER PRODUCT OVERVIEW 1 PRODUCT OVERVIEW OVER VIEW The KS57C0301/0302 single-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 KS57C0301/0302 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.
