1/4- to 1/11 Duty VFD Controller/Driver
AD6312
Features
˙4-pin serial interface
˙Key scanning (6× 4 matrices)
˙Programming display modes (11-segments & 11-
digits to 16-segments & 6-digits)
˙Programming dimming step
˙High-voltage output (VDD-35V max).
˙4 channels LED ports.
˙4-pin General-purpose input port
˙Built-in oscillator
˙No external resistor necessary for driver outputs
General Description
The AD6312 is a VFD (Vacuum Fluorescent
Display) controller/driver that is driven on a 1/4- to
1/11 duty factor (include key scan). It consists of 5
segment output lines, 6 segment/key scan 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
AD6312 through a four-line serial interface.

1.3 Address setting commands
These commands set an address of the display memory. If address 16H or higher is set, data is ignored,
until a valid address is set. On power application, the address is set to 00H.

110: Sets pulse width to 13/16.
111: Sets pulse width to 14/16.
Tums on/off display.
0: Display off (key scan continues)
1: Display on
On power application, the 1/16-pulse width is set, the display is turned off and key scanning is stopped.
2.0 Display RAM Address and Display Mode
The display RAM stores the data transmitted from an external device to the AD6312 through the serial
interface, and is assigned addresses as follows, in 8 bits unit:
