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.
