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.
