MOS INTEGRATED CIRCUIT
PD16311
1/8- to 1/16-DUTY FIPTM (VFD) CONTROLLER/DRIVER
The PD16311 is a FIP (Fluorescent Indicator Panel or Vacuum Fluorescent Display) controller/driver that is
driven on a 1/8- to 1/16 duty factor. It consists of 12 segment output lines, 8 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 PD16311 through a
three-line serial interface. This FIP controller/driver is ideal as a peripheral device of a single-chip microcomputer.
FEATURES
• Many display modes (12-segment & 16-digit to 20-segment & 8-digit)
• Key scanning (12  4 matrices)
• Dimming circuit (eight steps)
• High-voltage output (VDD  35 V max).
• LED ports (5 chs., 20 mA max).
• General-purpose input port (4 bits)
• No external resistor necessary for driver outputs (P-ch open-drain + pull-down resistor output)
• Serial interface (CLK, STB, DIN, DOUT)
