com TP6311 1/8 TO 1/16-DUTY VFD CONTROLLER General Description The TP6311 is a VFD (Vacuum Fluorescent Display) controller/driver that is driven on a 1/8 to 1/16-duty factor.
It consists of 12 segment output lines, 8 grid output lines, 8 segment/grid output drivelines, a display memory, a control circuit, and a key scan circuit.
Serial data is input to TP6311 through a This VFD controller/driver three-line serial interface.
microcomputer.
Features Multiple display modes (12-segment & 16-digit to 20-segment & 8-digit) Key scanning (12×4 matrices) Dimming circuit (eight steps) High-voltage output (VDD – 35V max) LED ports (5 chs, 20 mA max) General-purpose input port (4 bits) No external resistor necessary for driver outputs (P-ch open-drain + pull-down resistor output) Serial interface (CLK, STB, DIN, DOUT) is ideal as a peripheral device of a single-chip Ordering Information TP 6311 Footprint Version Package Type Package Type Q: QFP Footprint L: 3.
