LC75813T集成电路（IC）的显示驱动器规格书PDF中文资料

LC75813T属于集成电路（IC）的显示驱动器。由安森美半导体制造生产的LC75813T显示驱动器显示驱动器是一种集成电路 (IC)，可在微处理器 (MPU)、微控制器 (MCU) 或其他电路系统之间提供转换、接口和控制，用于 LCD、LED、OLED、DLP、真空荧光和 AMOLED 等显示器。可能的通信接口和协议包括模拟、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.

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 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
