鍵盤(pán)解碼器和I/O擴(kuò)展器

ADP5589是一款19通道GPIO（通用輸入/輸出）端口擴(kuò)展器，內(nèi)置鍵盤(pán)矩陣解碼器、可編程邏輯、復(fù)位邏輯和PWM發(fā)生器。該IC支持QWERTY鍵盤(pán)和GPIO擴(kuò)展。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 ADP5589處理所有按鍵掃描和解碼，并通過(guò)一條中斷線(xiàn)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。ADP5589配有一個(gè)FIFO，它最多可以存儲(chǔ)16個(gè)事件。 ? 16單元FIFO用于記錄事件\n? 19個(gè)可配置I/O支持多種功能\n? 鍵盤(pán)解碼支持最大11 x 8的矩陣\n? 按鍵/釋放中斷\n? 鍵盤(pán)鎖定/解鎖\n? GPIO功能\n? GPI支持可選的中斷級(jí)\n? 100 kΩ/300 kΩ上拉電阻\n? 300 kΩ下拉電阻\n? GPO支持推挽或開(kāi)漏輸出\n? 兩個(gè)可編程邏輯模塊\n? PWM發(fā)生器\n內(nèi)部生成PWM\n內(nèi)部與外部PWM求和(AND) \n? 時(shí)鐘分頻器 \n? 復(fù)位發(fā)生器\n? I2C 接口支持增強(qiáng)快速模式(Fm+) ，數(shù)據(jù)速率最高可達(dá)1 Mbps \n? 開(kāi)漏中斷輸出\n? 24引腳LFCSP封裝;
