1 / 16 page  1/16 May 2004 s MANY DISPLAY MODES (11 SEGMENTS & 11 DIGITS TO 16 SEGMENTS & 4 DIGITS) s KEY SCANNING (6 x 4 MATRIX) s DIMMING CIRCUIT (EIGHT STEPS) s HIGH-VOLTAGE OUTPUT (VDD –35V MAX) s LED PORTS (4 CHS, 20mA MAX) s GENERAL PURPOSE INPUT PORT (4 bits) s NO EXTERNAL RESISTOR NECESSARY FOR DRIVER OUTPUT (P-CH OPEN DRAIN + PULL DOWN RESISTOR OUTPUT) s 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.
