UPD16315 Description
The µPD16315 is a FIP (Fluorescent Indicator Panel, or Vacuum Fluorescent Display) controller/driver that is driven on a 1/4- to 1/12- duty factor. It consists of 16 segment output lines, 4 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 µPD16315 through a three-line serial interface.
