PT6324
PT6324 is VFD Driver/Controller manufactured by PTC.
PT6324 is a Vacuum Fluorescent Display (VFD) Controller driven on a 1/8 to 1/16 duty factor housed in 52-pin plastic LQFP. 24 segment output lines, 16 grid output 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 puter. Serial data is fed to PT6324 via a three-line serial interface.
