1 / 24 page March 2006 Rev 2 1/24 24 STM86312 1/4 to 1/11-duty VFD controller/driver General features ■ 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) Description 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.
