SC75823

Silan Semiconductors 1/3 DUTY GENERAL-PURPOSE LCD DRIVER DESCRIPTION The SC75823 is a general-purpose LCD driver that can be used for frequency display in microprocessor-controlled radio receives and in other display applications. In addition to being able to directly drive up to 156 LCD segments. SC75823 QFP-64-14x14-0.8 FEATURES Supports both 1/3 duty 1/2 bias and 1/3 duty 1/3 bias LCD drive of up to 156 segments under serial data control. Serial data input supports CCB format communication with the system controller. Serial data control of the power-saving mode based backup function and all the segments forced off function. High generality since display data is displayed directly without decoder intervention. The INH pin can force the display to the off state. The LCD drive bias voltage can be provided internally or externally. Power supply voltage: 4.5 to 6.0V LQFP-64-10 x 10-0.5 ORDERING INFORMATION Device SC75823A SC75823B Package LQFP-64-10 X 10-0.5 QFP-64-14 X 14-0.8 BLOCK DIAGRAM COM1 COM2 COM3 S52 S51 S1 VDD1 Common Driver VDD2 Latch & Driver INH Shift Register OSC Clock Generator Address Detector DI CL CE VDD VSS HANGZHOU SILAN MICROELECTRONICS JOINT-STOCK CO.,LTD Rev: 1.1 2002.03.04 1 Silan Semiconductors PIN CONFIGURATION S48 S47 S46 S45 S44 S43 S42 S41 S40 S39 S38 S37 S36 S35 S34 34 SC75823 S33 33 32 S32 31 S31 30 S30 29 S29 28 S28 27 S27 26 S26 25 S25 24 S24 23 S23 22 S22 21 S21 20 S20 19 S19 18 S18 17 S17 16 S16 48 S49 49 S5...
