1/3 Duty LCD Display Drivers with Key Input Function
Overview
The LC75863E and LC75863W are 1/3 duty LCD display drivers that can directly drive up to 75 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.

Features
Key input function for up to 30 keys (A key scan is performed only when a key is pressed.) 1/3duty - 1/2bias and 1/3duty - 1/3bias drive schemes can be controlled from serial data (up to 75 segments). Sleep mode and all segments off functions that are controlled from serial data. Segment output port/general-purpose output port function switching that is 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. Independent VLCD for the LCD driver block (VLCD can be set to in the range VDD-0.5 to 6.0 volts.) Provision of an on-chip voltage-detection type reset circuit prevents incorrect displays. RC oscillator circuit.
