LC75808W

Ordering number : ENN6370A CMOS IC LC75808E, 75808W 1/8 to 1/10 Duty LCD Display Drivers with Key Input Function Overview The LC75808E and LC75808W are 1/8 to 1/10 duty LCD display drivers that can directly drive up to 600 segments and can control up to four general-purpose output ports. These products also incorporate a key scan circuit that accepts input from up to 30 keys to reduce printed circuit board wiring. Package Dimensions unit: mm 3151-QFP100E [LC75808E] 0.825 0.575 80 81 0.65 23.2 20.0 0.3 1.6 0.575 51 50 0.15 Features Key input function for up to 30 keys (A key scan is performed only when a key is pressed.) 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 480 segments 1/9duty–1/4bias: up to 540 segments 1/10duty–1/4bias: up to 600 segments Sleep mode and all segments off functions that are controlled from serial data. Serial data I/O supports CCB format communication with the system controller. 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. Provision of an on-chip voltage-detection type reset circuit prevents incorrect displays. The INH pin is provided. This pin turns off the display, disables key scanning, and forces the general-purpose output ports to the low level. RC osc...
