LC75833WHS-E

LCD DRVR 3.3V/5V 48Pin SQFP

The LC75833W is a 1/3-duty general-purpose LCD display driver that can be used for frequency display in electronic tuners under the control of a microcontroller. The LC75833W can drive an LCD with up to 105 segments directly. The LC75833W can also control up to 8 general-purpose output ports. Since the LC75833W 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.
