1/4 to 1/11 DUTY FIP(VFD)
CONTROLLER/DRIVER
DESCRIPTION
The SC16312 is a FIP (Fluorescent Indicator Panel, or Vacuum
Fluorescent Display) controller/driver that is driven on a 1/4 or 1/11
duty factor. It consists of 11 segment output lines, 6 grid output lines,
5 segment/grid output drive lines, a display memory, a control circuit,
and a key scan circuit. Serial data is input to the SC16312 through a
three-line serial interface. This FIP controller/driver is ideal as a
peripheral device for a single-chip microcomputer.
SC16312
FEATURES
* Multiple display modes (11-segment & 11-dight
to 16-segment & 4-digit).
* Key scanning (6x4 matrix).
* Dimming circuit (eight steps).
* High-voltage output (V
