帶有中斷的I2C總線遠(yuǎn)程16位I/O擴(kuò)展器

PCA8575通過(guò)兩路雙向I2C總線（串行時(shí)鐘(SCL)、串行數(shù)據(jù)(SDA)）為大多數(shù)微控制器系列提供通用遠(yuǎn)程I/O擴(kuò)展。\n器件由16位準(zhǔn)雙向端口和I2C總線接口組成。PCA8575具有低電流消耗且包含具備高電流驅(qū)動(dòng)能力的鎖存輸出，用于直接驅(qū)動(dòng)LED。\nPCA8575還具有中斷線路\n，可連接至微控制器的中斷邏輯。通過(guò)在此線路發(fā)送中斷信號(hào)，遠(yuǎn)程I/O可通知微控制器其端口上是否存在輸入數(shù)據(jù)而無(wú)需通過(guò)I2C總線通信。內(nèi)部上電復(fù)位(POR)會(huì)將I/O初始化為輸入。\n; 400 kHz I2C總線接口\n2.3 V至5.5 V 操作，5.5 V耐受I/O\n16位遠(yuǎn)程I/O引腳在上電時(shí)默認(rèn)為輸入\n閉鎖輸出具有25 mA的灌電流能力，可直接驅(qū)動(dòng)LED\n總封裝灌電流能力為400 mA\n低電平有效的開漏中斷輸出\n使用3個(gè)地址引腳的8個(gè)可編程從地址\n可讀取器件ID（制造商、器件類型和版本）\n低待機(jī)電流（最大10 uA）\n-40 Cel至+85 Cel操作\nESD保護(hù)：按JESD22-A114超過(guò)2000 V HBM，按JESD22-A115超過(guò)200 V MM，按JESD22-C101超過(guò)1000 V CDM\n已按照J(rèn)EDEC標(biāo)準(zhǔn)JESD78完成閉鎖;
