DATA SHEET MOS INTEGRATED CIRCUIT µPD16312 1/4- to 1/11-DUTY FIPTM (VFD) CONTROLLER/DRIVER 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. 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 x 4 matrix • Dimming circuit: 8 steps • High-withstanding-voltage output: VDD − 35 V MAX. • LED ports: 4 ch, 20 mA MAX.
