General Purpose LCD Driver
PT6533
DESCRIPTION
PT6533 is a general purpose LCD Driver IC utilizing CMOS technology specially designed with
character and graphical displays. It provides1/4 duty, 1/8 duty and can drive up to a maximum of 232
segments drivers. Housed in a 44-pin LQFP package, PT6533 can directly display the display data
without any decoder intervention, thereby providing a high level of generality. Built-in display contrast
adjustment circuit, independent LCD drive block power supply and serial data control of the power
saving mode based on the backup function as well as all segments forced OFF functions are
incorporated into a single chip having the highest performance and reliability. Pin assignments and
application circuits are optimized for easy PCB layout and cost saving benefits.
