PT6302
VFD Driver/Controller IC with Character RAM
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.
