PT6554_10 Datasheet, PDF (1/30 Pages) Princeton Technology Corp – LCD Driver IC

DESCRIPTION
PT6554 is a high performance Liquid Crystal Display
(LCD) Driver IC utilizing CMOS technology specially
designed with Key Input function. It can drive up to a
maximum of 164 segments and control up to 4 general
purpose output ports. It includes a Key Scan Circuit
that can support up to 30 key inputs and provides
On-Chip Voltage Detection Type Reset Circuit which
prevents incorrect display. Display Data can be
directly displayed without using any decoder. PT6554
also supports both 1/4 duty-1/2 bias and 1/4 duty-1/3
bias drive techniques. Pin assignments and
application circuit are optimized for easy PCB Layout
and cost saving advantages.
