PT6324_10 Datasheet, PDF (1/16 Pages) Princeton Technology Corp – VFD Driver/Controller IC

DESCRIPTION
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 computer. Serial data is fed to PT6324 via a
three-line serial interface.
APPLICATIONS
• Microcomputer peripheral devices
• Digital Audio/Video system: CD/MD/VCD/DVD
players
• Car audio
• VCR
• Electric scale meter
• P.O.S.
• Electronic equipment with instructional display
