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

application circuit are optimized for easy PCB Layout

and cost saving advantages.
