LC75884W

Ordering number : EN6086 CMOS IC LC75884E, LC75884W 1/4 Duty LCD Display Drivers with Key Input Function Overview The LC75884E and LC75884W are 1/4 duty LCD display drivers that can directly drive up to 220 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 QFP80E [LC75884E] 23.2 20.0 1.0 0.8 64 65 0.8 0.35 41 40 1.6 0.15 Key input function for up to 30 keys (A key scan is performed only when a key is pressed.) 1/4duty - 1/2bias and 1/4duty - 1/3bias drive schemes can be controlled from serial data (up to 220 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. RES pin provided for forcibly initializing the IC internal circuits.
