PT6315

VFD Driver/Controller IC

DESCRIPTION

FEATURES

PT6315 is a Vacuum Fluorescent Display (VFD)

Controller driven on a 1/4 to 1/12 duty factor. Sixteen

•

CMOS Technology

Low Power Consumption

Key Scanning (16 x 2 matrix)

Multiple Display Modes: (16 segments, 12 digits to

24 segments, 4 digits)

segment output lines,

grid output lines,

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

PT6315 via a three-line serial interface. It is housed in

a 44-pin LQFP.

•

8-Step Dimming Circuitry

LED Ports Provide (4 channels, 20mA max.)

Serial Interface for Clock, Data Input, Data Output,

Strobe Pins

•

No External Resistors Needed for Driver Outputs

Available in 44-pin LQFP
