The STM86312 is a VFD (Vacuum Fluorescent Display) controller/driver that is driven on a 1/4 to 1/11-duty factor.

Many display modes (11 segments & 11 digits to 16 segments & 4 digits).
Key scanning (6 x 4 matrix).
Dimming circuit (eight steps).
High-voltage output (VDD.
35V max).
LED ports (4 chs, 20mA max).
General purpose input port (4 bits).
No external resistor necessary for driver output (P-channel open drain + pull down resistor output).
Serial interface (CLK, STB, DIN, DOUT) PQFP44.
