LC75878E

Ordering number : ENN*6473 CMOS IC LC75878E, 75878W 1/8 to 1/10 Duty General-Purpose LCD Display Drivers Preliminary Overview The LC75878E and LC75878W are 1/8 to 1/10 duty general-purpose LCD display drivers used for character and graphics display. These products operate under the control of a microcontroller and can directly drive an LCD with up to 730 segments. They can also control up to 4 general-purpose output ports. Package Dimensions unit: mm 3151-QFP100E [LC75878E] 0.825 0.575 80 81 0.65 23.2 20.0 0.3 1.6 0.575 51 50 0.15 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 600 segments 1/9duty–1/4bias: up to 666 segments 1/10duty–1/4bias: up to 730 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 4 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.
