LC75839PW-H

Overview
The LC75834E, LC75834W, and LC75834JE are 1/4 duty general-purpose LCD drivers that can be used for frequency display in electronic tuners under the control of a microcontroller.
The LC75834E and LC75834W can drive an LCD with up to 136 segments directly, the LC75834JE can drive an LCD with up to 120 segments directly.
Features
• Supports both 1/4 duty 1/2 bias and 1/4 duty 1/3 bias LCD drive under serial data control. LC75834E, LC75834W: up to 136 segments LC75834JE: up to 120 segments(without the S9, S18, S27, S34 segment output pins from the LC75834E, LC75834W)
• Serial data input supports CCB format communication with the system controller.
• Serial data control of the power-saving mode based backup function and all the segments forced off function
• Serial data control of switching between the segment output port and the general-purpose output port functions
• High generality, since display data is displayed directly without decoder intervention.
• Independent VLCDfor the LCD driver block (VLCD can be set to any voltage in the range 2.7 to 6.0 volts, regardless of the logic block power-supply voltage.)
•
The INH pin can force the display to the off state.
• RC oscillator circuit
