PT6355
DESCRIPTION
PT6355 is a Vacuum Fluorescent Display Controller driven 5/16, 6/16, 14/16 and 15/16 duty factors. Eight to
Eighteen Segment Output Lines, Seven to Ten Grid Output Lines, Ten Segment/Grid Output Drive Lines, 8-bit
x 6-channel A-D Converter, Built-in Noise Filter are all incorporated into a single chip to build a highly reliable
peripheral device for a single chip micro-computer. PT6355 also provides 4 serial interfaces via the CS, SIN,
SOUT, SCLK Pins. Housed in 44-pin, LQFP Package, PT6355's pin assignment and application circuit are
optimized for easy PCB layout and cost saving benefits.
