| Ordering number:ENN4467 CMOS IC LC75850E, 75850W 1/3 Duty General Purpose LCD Drivers Overview The LC75850E and LC75850W are general purpose LCD drivers for use in microprocessor controlled applications such as radio tuner frequency displays. Package Dimensions unit:mm 3159-QIP64E [LC75850E] 17.2 1.0 0.8 14.0 0.35 33 1.6 1.0 0.15 32 Functions * Supports both 1/3 duty 1/2 bias and 1/3 duty 1/3 bias LCD driver techniques for a maximum of 156 segments. * Power saving mode allows the backup function to be switched on or off and all segments to be turned off unconditionally. * Can be controlled by three serial data lines (CE, CL, and DI) from the microprocessor. (CCB handling) * High generality, since segment data can be displayed without going through a decoder. * The INH pin unconditionally turns off display. * The LCD drive bias voltage can be provided internally or externally. * Power supply voltage: 4.5 to 8V. 1.6 1.0 49 48 17.2 14.0 0.8 17 1.0 1 16 3.0max 0.8 64 0.1 2.7 15.6 SANYO : QIP64E unit:mm 3190-SQFP64 [LC75850W] 12.0 10.0 0.18 1.25 48 49 1.25 0.5 1.25 33 32 0.15 12.0 10.0 0.5 1 16 0.5 0.1 Any and all SANYO products described or contained herein do not have specifications that can handle applications that require extremely high levels of reliability, such as life-support systems, aircraft's control systems, or other applications whose failure can be reasonably expected to result in serious physical and/or material damage.

When the data transfer has completed, set INH high. This will prevent meaningless displays at power on.
