VFD Driver/Controller IC

PT6312

DESCRIPTION

PT6312 is a Vacuum Fluorescent Display (VFD) Controller driven on a 1/4 to 1/11 duty factor. Eleven

segment output lines, 6 grid output lines, 5 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 PT6312 via a three-line serial interface. It

is housed in a 44-pin plastic LQFP Package and is functionally compatible with µpD16312.

FEATURES

• CMOS technology

• Low power consumption

• Key scanning (6 x 4 matrix)

• Multiple display modes: (11 segments, 11 digits to 16 segments, 6 digits)

• 8-Step dimming circuitry

• LED ports provided (4 channels, 20mA max.)

• 4- Bits general purpose input ports provided

• Serial interface for Clock, Data Input, Data Output, Strobe pins

• No external resistors needed for driver outputs

• Functional compatibility with µpD16312

• Available in 44-pin, LQFP package

APPLICATION

• Microcomputer peripheral devices
