The TP6312 is a VFD (Vacuum Fluorescent Display) controller/driver that is driven on a 1/4 to 1/11-duty factor. It consists of 11 segment output lines, 6 grid output lines, 5 segment/grid output drivelines, a display memory, a control circuit, and a Key scan circuit. Serial data is input to TP6312 through a three-line serial interface. This VFD controller/driver is ideal as a peripheral device of a single-chip microcomputer
