VFD Driver/Controller IC
PT6311
DESCRIPTION
PT6311 is a Vacuum Fluorescent Display (VFD) Controller driven on a 1/8 to 1/16 duty factor housed in
52-pin plastic QFP 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 PT6311
via a three-line serial interface.
