PT6302
DESCRIPTION
PT6302 is a dot matrix VFD Driver/Controller IC utilizing CMOS Technology specially designed to
display characters, numerals, and symbols. PT6302 provides 35 dot matrix plus 2 additional segment
drivers and 16 grid drivers. 248 types of character data (CGROM), 8 types of character data (CGRAM),
16 display digits x 2 bits symbol data, 16 display digits x 8 bits register for character data display and 2
general output bits for static operation are provided. Pin assignments and application circuit are
optimized for easy PCB layout and cost saving advantages.
