LC75847T数据手册集成电路（IC）的显示驱动器规格书PDF

描述 Description

The LC75847T is 1/3 duty and 1/4 duty general-purpose LCD driver that can be used for frequency display in electronic tuners under the control of a microcontroller. The LC75847T can drive an LCD with up to 420 segments directly. The LC75847T can also control up to 8 general-purpose output ports.

特性 Features

• Switching between 1/3 duty and 1/4 duty drive techniques under serial data control.
• Switching between 1/2 bias and 1/3 bias drive techniques under serial data control.
• Up to 318 segments for 1/3 duty drive and 420 segments for 1/4 duty drive can be displayed.
• Serial data input supports 'computer control bus' 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.
• Serial data control of frame frequency for common and segment output waveforms.
• High generality, since display data is displayed directly without decoder intervention.
• Built-in display contrast adjustment circuit
• Independent VLCD for the LCD driver block
• The INH pin can force the display to the off state.
• RC oscillator circuit
