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.

Notes:
1. The value of Rosc is depend on PT6324 IC chip supply voltage of VDD (Rosc=82K , when VDD=5V; Rosc=100K , when VDD=3.3V).
2. Z1, Z2=Zener diode 5.1V
3. Please adding the current amplifying circuit as following figure when IOHGR>15mA on VFD panel for high brightness issue.
