uPD16312 Datasheet VFD CONTROLLER/DRIVER

Manufacturer: Renesas

General Description

The µPD16312 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 µPD16312 through a three-line serial interface.
