LC75814V

Ordering number : EN6792 LC75814V CMOS LSI 1/4 Duty General-Purpose LCD Driver http://onsemi.com Overview The LC75814V is a 1/4 duty general-purpose LCD driver that can be used for frequency display in electronic tuners under the control of a microcontroller. The LC75814V can drive an LCD with up to 64 segments directly. The LC75814V can also control up to 4 generalpurpose output ports. Since the LC75814V uses separate power supply systems for the LCD drive block and the logic block, the LCD driver block power-supply voltage can be set to any voltage in the range 2.7 to 6.0 volts, regardless of the logic block power-supply voltage. Features  Support for 1/4 duty 1/2 bias or 1/4 duty 1/3 bias drive of up to 64 segments under serial data control.  Serial data input supports CCB format communication with the system controller.  Serial data control of the power-saving mode based backup function and all the segments forced off function  Serial data control of switching between the segment output port and the general-purpose output port functions  High generality, since display data is displayed directly without decoder intervention.  Independent VLCD for the LCD driver block (VLCD can be set to any voltage in the range 2.7 to 6.0 volts, regardless of the logic block power-supply voltage.)  The INH pin can force the display to the off state.  RC oscillator circuit SSOP30(275mil) Package Dimensions unit : mm (typ) 9.75 30 1 0.65 (0.33) 0.22 0.15 0.1 (1.3) 5.6 1.5 MAX ...
