鍵盤解碼器和I/O擴(kuò)展器

ADP5585是一款10I/O端口擴(kuò)展器，內(nèi)置鍵盤矩陣解碼器、可編程邏輯、復(fù)位發(fā)生器和PWM發(fā)生器。I/O擴(kuò)展器IC適用于便攜式設(shè)備（手機(jī)、遙控器和相機(jī)）及非便攜式應(yīng)用（醫(yī)療保健、工業(yè)和儀器儀表），可用來(lái)增加處理器可用的I/O數(shù)量，或者通過(guò)接口連接器減少前面板設(shè)計(jì)所需的I/O數(shù)量。\n\n ADP5585處理所有按鍵掃描和解碼，并通過(guò)一條中斷線通知主處理器有新的按鍵事件發(fā)生。GPI變化和邏輯變化也可以通過(guò)FIFO記錄為事件，從而無(wú)需監(jiān)控不同的寄存器來(lái)判斷事件變化。ADP5585配有一個(gè)FIFO，它最多可以存儲(chǔ)16個(gè)事件。處理器可以通過(guò)I2C兼容型接口回讀事件。\n\n AD ? 16單元FIFO用于記錄事件 \n? 10個(gè)可配置I/O\n? 鍵盤解碼，支持的最大矩陣為5x5，提供一個(gè)11 GPIO (5x6)選項(xiàng)\n? 按鍵/釋放中斷\n?
