LC75813E屬于集成電路（IC）的顯示驅(qū)動(dòng)器。由安森美半導(dǎo)體公司制造生產(chǎn)的LC75813E顯示驅(qū)動(dòng)器顯示驅(qū)動(dòng)器是一種集成電路 (IC)，可在微處理器 (MPU)、微控制器 (MCU) 或其他電路系統(tǒng)之間提供轉(zhuǎn)換、接口和控制，用于 LCD、LED、OLED、DLP、真空熒光和 AMOLED 等顯示器。可能的通信接口和協(xié)議包括模擬、BCD、I2C、并行、串行、SMBus、SPI 和 QSPI。

Overview

The LC75813E and LC75813T are 1/3 duty and 1/4 duty general-purpose LCD drivers that can be used for frequency display in electronic tuners under the control of a microcontroller. The LC75813E and LC75813T can drive an LCD with up to 344 segments directly. The LC75813E and LC75813T can also control up to 8 general-purpose output ports. Since the LC75813E and LC75813T use separate power supply systems for the LCD drive block and the logic block, the LCD driver block power-supply voltage can be set to any voltage in the range 2.7 to 6.0 volts, regardless of the logic block power supply voltage.

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 261 segments for 1/3 duty drive and 344 segments for 1/4 duty drive can be displayed.

? 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.

? Serial data control of frame frequency for common and segment output waveforms.

? High generality, since display data is displayed directly without decoder intervention.

? Independent VLCD for 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 powersupply voltage.)

? The INH pin can force the display to the off state.

? RC oscillator circuit
