General Description
The AD6311 is a VFD (Vacuum Fluorescent
Display) controller/driver that is driven on a 1/8- to
1/16 duty factor (include key scan). It consists of 12
segment/key scan 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 AD6311 through a four-line serial
interface.
