PT6315
VFD Driver/Controller IC
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.
