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.
