LC75838W CMOS LSI 1/8 to 1/10 Duty General-Purpose LCD Driver www.onsemi.com Overview The LC75838W is 1/8 to 1/10 duty general-purpose LCD display driver used for character and graphics display. This product operates under the control of a microcontroller and can directly drive an LCD with up to 380 segments. It can also control up to 3 general-purpose output ports. SPQFP64 10x10 / SQFP64 Features  1/8duty–1/4bias, 1/9duty–1/4bias, and 1/10duty–1/4bias drive schemes can be controlled from serial data. 1/8duty–1/4bias: up to 320 segments 1/9duty–1/4bias: up to 351 segments 1/10duty–1/4bias: up to 380 segments  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.  Direct display of display data without the use of a decoder provides high generality.  Built-in display contrast adjustment circuit.  Up to 3 general-purpose output ports are included.  Independent LCD driver block power supply VLCD.  The INH pin is provided. This pin turns off the display and forces the general-purpose output ports to the low level.  RC oscillator circuit  CCB is ON Semiconductor® ’s original format. All addresses are managed by ON Semiconductor® for this format.  CCB is a registered trademark of Semiconductor Components Industries, LLC.
