VFD CONTROLLER/DRIVER
The SC16311 is a FIP (Fluorescent Indicator Panel or Vacuum
Fluorescent Display) controller/driver that is driven on a 1/8- to 1/16
duty factor. It consists of 12 segment output lines, 8 grid output lines,
8 segment/grid output drive lines, a display memory, a control circuit,
and a key scan circuit. Serial data is input to the SC16311 through a
three-line serial interface. This FIP controller/driver is ideal as a
peripheral device of a single-chip microcomputer.
