1、nokia5110显示器介绍
这款液晶显示屏是通过PCD8554驱动控制器来驱动的，主要的特征如下：
单芯片 LCD 控制/驱动
48 行，84 列输出
显示数据 RAM 48*84 位
芯片集成：
——LCD电压发生器（也可以使用外部电压供应）
——LCD偏置电压发生器
——振荡器不需要外接元件（也可以使用外部时钟）
外部 RES（复位）输入引脚
串行界面最高4.0Mbits/S
CMOS兼容输入
混合速率：48
逻辑电压范围VDD到 VSS：2.7V~3.3V
显示电压范围VLCD到 VSS：
——6.0~8.5V LCD内部电压发生器（充许电压发生器）
——6.0~9.0V LCD外部电压供应（电压发生器关闭）
低功耗，适用于电池供电系统
关于VLCD的温度补偿
使用温度范围：-25~70℃
PCD8544 是一块低功耗的CMOS LCD控制驱动器，设计为驱动48 行84 列的图形显示。所有必须的显示功能集成在一块芯片上，包括LCD 电压及偏置电压发生器，只须很少外部元件且功耗小。 PCD8544 与微控制器的接口使用串行总线。PCD8544 采用 CMOS工艺。
