STM86312 Datasheet | STMicroelectronics

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, 20m A 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 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 microputer.
