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.
