LC75827E

Ordering number : ENN7665 CMOS LSI LC75827E, 75827W 1/3, 1/4 Duty General-Purpose LCD Driver Overview The LC75827E and LC75827W are 1/3, 1/4 duty generalpurpose LCD drivers that can be used for frequency display in electronic tuners under the control of a microcontroller. 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. Features Either 1/3 or 1/4 duty can be selected with the serial control data. Either 1/2 or 1/3 bias can be selected with the serial control data. Up to 153 segments can be driven in 1/3 duty drive and up to 200 segments can be driven in 1/4 duty drive. Serial data input supports CCB* format communication with the system ...
