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. FEATURES * CMOS technology * Wide variety of bias drive techniques: - 1/8 duty, 1/4 bias drive technique: (232 segments max.) - 1/4 duty, 1/4 bias drive technique: (132 segments max.) * RC oscillation circuit * Direct display of display data without any decoder intervention * Serial data control of the power saving mode based backup function * Available in C.O.B. or 44-pin LQFP packages APPLICATIONS * * * Car Audio display Consumer display Household electronic application PT6533 V1.0 -1- May, 2007 Tel: 886-2-66296288 Fax: 886-2-29174598 URL: http://www.princeton.com.tw General Purpose LCD Driver PT6533 37 COM1 36 COM2 35 COM3 43 CLK 34 COM4 PIN CONFIGURATION 38 VLCD 40 OSC 41 VDD 39 VSS 42 CE 44 DI SG1 SG2 SG3 SG4 SG5 SG6 SG7 SG8 SG9 1 2 3 4 5 6 7 8 9 33 COM5/SG33 32 COM6/SG32 31 COM7/SG31 30 COM8/SG30 29 SG29 PT6533-LQ 28 SG28 27 SG27 26 SG26 25 SG25 24 SG24 23 SG23 SG10 10 SG11 11 SG15 15 SG19 19 SG12 12 SG14 14 SG18 18 SG20 20 SG21 21 SG13 13 SG16 16 PT6533 V1.0 -2- SG17 17 SG22 22 May, 2007 Tel: 886-2-66296288 Fax: 886-2-29174598 URL: http://www.princeton.com.tw General Purpose LCD Driver PT6533 APPLICATION CIRCUIT 1/8 DUTY, 1/4 BIAS DRIVE TECHNIQUE (for Normal Panel Use) PT6533 V1.0 -3- May, 2007 Tel: 886-2-66296288 Fax: 886-2-29174598 URL: http://www.princeton.com.tw General Purpose LCD Driver PT6533 ORDER INFORMATION Valid Part Number PT6533-LQ PT6533-H Package Type 44 Pins, LQFP C.O.B.
