1/3 Duty 1/4 Duty LCD Display Driver

The LC75827E and LC75827W are 1/3, 1/4 duty general- purpose 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. By Sanyo Semiconductor Corporation
