The

PD16312 is a FIP (fluorescent Indicator Panel, or Vacuum Fluorescent Display) controller/driver that is

driven on a 1/4- to 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

PD16312 through a

three-line serial interface. This FIP controller/driver is ideal as a peripheral device for a single-chip microcomputer.

FEATURES

• Multiple display modes (11-segment & 11-digit to 16-segment & 4-digit)

• Key scanning (6

4 matrix)

• Dimming circuit (eight steps)

 35 V max).

• LED ports (4 chs., 20 mA max).

• General-purpose input port (4 bits)

• No external resistors necessary for driver outputs (P-ch open-drain + pull-down resistor output)
