8字符4行點(diǎn)矩陣LCD控制驅(qū)動器，帶擴(kuò)展功能

NJU6426是點(diǎn)矩陣LCD控制驅(qū)動器，單芯片或結(jié)合一些擴(kuò)展驅(qū)動器可用于帶圖標(biāo)的8字符或最多24字符4行顯示。它包含電壓轉(zhuǎn)換器、泄放電阻、CR振蕩器和微處理器接口電路。它包含指令解碼控制器、字符生成器ROM/RAM、高電壓工作common和segment驅(qū)動器和擴(kuò)展驅(qū)動器接口電路。電壓轉(zhuǎn)換器和泄放電阻將單電源（5V）轉(zhuǎn)換為大約2倍的電壓（10V）和用于內(nèi)部LCD驅(qū)動波形的偏置電壓。所以，盡管電源電路簡單，仍可實(shí)現(xiàn)高對比度顯示。CR振蕩器集成C和R，所以振蕩無需外接組件。微處理器接口電路以2MHz頻率工作，可直接連接到4/8位微處理器。字符生成器包含9，600位ROM和64字節(jié)RAM。33Com; ? 8字符4行點(diǎn)矩陣LCD控制驅(qū)動器\n? 最多顯示80個圖標(biāo) (使用COM33)\n? 4/8位微處理器直接接口\n? 顯示數(shù)據(jù)RAM-96×8位 (最多24-字符4-行顯示)\n? 字符生成器ROM-9，600位 (240個5×7點(diǎn)的字符)\n? 字符生成器RAM-64×8位 (8圖案（5×7點(diǎn)）)\n? 高電壓LCD驅(qū)動器 (33-common/40-segment)\n? 有用的指令集 (清屏、返回首頁、顯示ON/OFF控制、游標(biāo)ON/OFF控制、閃爍顯示、游標(biāo)移位、字符移位)\n? 擴(kuò)展功能\n? 加電初始化\n? 硬件復(fù)位功能\n? 低功耗\n? 芯片集成電壓轉(zhuǎn)換器和泄放電阻\n?;
