LC75827E Overview
In addition to being able to directly drive up to 200 LCD segments, the LC75827E and LC75827W can also control up to 12 general-purpose output ports. The LC75827E/W uses separate power supplies for the LCD driver block and the logic block. This allows the LCD driver block supply voltage to be set to any level in the 2.7 to 6.0 V range independently of the logic block supply voltage.
