AIP1668 is  an LED Controller  driven on a  1/5 to 1/8 duty  factor. 10 segment  output lines, 4  grid output

lines,  3   segment/  grid  output   lines,  one  display   memory,  control  circuit,   key  scan   circuit  are  all

incorporated into a single chip to build a highly reliable peripheral device  for a single chip microcomputer.

Serial data is fed  to AIP1668 via a three-line serial interface.  Housed in a 24 pins SOP Package,  AIP1668

pin assignments and application circuit are optimized for easy PCB Layout and cost saving advantages.
