LC75863E

Ordering number : ENN7135 CMOS IC LC75863E, 75863W 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. Package Dimensions unit: mm 3156-QIP48E [LC75863E] 1.5 1.6 1.5 36 37 1.0 17.2 14.0 0.35 1.6 1.5 25 24 0.15 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.
