DESCRIPTION

PT6311B is a Vacuum Fluorescent Display (VFD)

Controller driven on a 1/8 to 1/16 duty factor housed in

52-pin plastic LQFP Package. Twelve segment output

lines, 8 grid output lines, 8 segment/grid output drive

lines, one display memory, control circuit, key scan

circuit are all incorporated into a single chip to build a

highly reliable peripheral device for a single chip micro

computer. Serial data is fed to PT6311B via a

three-line serial interface.
