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)

Display RAM Address and Display Mode
The display RAM stores the data transmitted from an external device to the PD16311 through the serial interface,
and is assigned addresses as follows, in units of 8 bits:

Data reading command is set.
Data reading starts.
Because the DOUT pin is an N-ch, open-drain output pin, be sure to connect an external pull-up resistor to this pin
(1 k to 10 k).
*: When data is read, a wait time tWAIT of 1 s is necessary since the rising of the eighth clock that has set the
command, until the falling of the first clock that has read the data.
