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, 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.
