LC75813T-E

Segment Display LCD Driver 3.3V/5V 100Pin TQFP Tray

The LC75813T is the 1/3 duty and 1/4 duty general-purpose LCD driver that can be used for frequency display in electronic tuners under the control of a microcontroller. The LC75813T can drive an LCD with up to 344 segments directly. The LC75813T can also control up to 8 general-purpose output ports. Since the LC75813T use 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.
