  • The STM86312 is a VFD (Vacuum Fluorescent Display) controller/driver that is driven on a 1/4 to 1/11-duty factor. It consists of 11-segments output lines, 6 grid output lines, 5 segments/grid output drive lines, a display memory, a control circuit, and a key scan circuit. Serial data are input to the STM86312 through a three-line serial interface. This VFD controller/driver is ideal as a peripheral device for a single-chip microcomputer.

    Key Features

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