KS57C2102
4-BIT CMOS Microcontroller
KS57C2102 single-chip CMOS microcontroller designed high-performance using Samsung's advanced modular development approach, SAM4 (Samsung Arrangeable 4-bit Microcontrollers).Pull-up resistors assignable software four pins. Four vectored interrupts provide fast response system events. With direct drive capability digits), pins segment data output, versatile 8-bit timer/counter, basic timer, watch timer, KS57C2102 excellent design solution wide variety general-purpose applications.
