LC75804W

Ordering number : ENN6266A CMOS IC LC75804E, LC75804W 1/3, 1/4 Duty LCD Display Drivers with Key Input Function Overview The LC75804E and LC75804W are 1/3 duty and 1/4 duty LCD display drivers that can directly drive up to 300 segments and can control up to eight 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 3151A-QFP100E [LC75804E] 23.2 80 81 51 50 14.0 1.6max Key input function for up to 30 keys (A key scan is performed only when a key is pressed.) 1/3 duty and 1/4 duty drive schemes can be controlled from serial data. 1/2 bias and 1/3 bias drive schemes can be controlled from serial data. Capable of driving up to 228 segments using 1/3 duty and up to 300 segments using 1/4 duty. 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. RC oscillator circuit. CCB...
