PT6315

VFD Driver/Controller IC

Princeton Technology 

DESCRIPTION

PT6315 is a Vacuum Fluorescent Display (VFD)

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

segment output lines, 4 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

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

a 44-pin LQFP.

APPLICATION

• Microcomputer Peripheral Devices
