Diodes 公司推出符合汽车规格的双电源轨 I2C 总线 GPIO 扩充器，提升系统设计与弹性

<p><span>Diodes<span>&nbsp;</span></span><span>公司</span><span><span>&nbsp;</span>(Nasdaq</span><span>：</span><span><span>DIOD)<span>&nbsp;</span></span></span><span><span>宣布针对汽车应用推出</span></span><span><span><span>&nbsp;</span>16<span>&nbsp;</span></span></span><span><span>位</span></span><span><span><span>&nbsp;</span></span></span><a href="https://www.diodes.com/part/PI4IOE5V6416Q"><span>PI4IOE5V6416Q</span></… href="https://www.diodes.com/part/PI4IOE5V6534Q"><span>PI4IOE5V6534Q</span></… (GPIO)<span>&nbsp;</span></span><span>扩充器。这些符合汽车规格与取得</span><span><span>&nbsp;</span>AEC-Q100 Grade 2<span>&nbsp;</span></span><span>认证的双电压轨装置，代表用于汽车业的首创之举，透过</span><span><span>&nbsp;</span>I2C<span>&nbsp;</span></span><span>接口为新世代低电压微处理器及微控制器，提供更强大的可编程</span><span><span>&nbsp;</span>I/O</span><span>。</span></p>

<p><span>作为</span><span><span>&nbsp;</span>Diodes<span>&nbsp;</span></span><span>持续进军汽车业之计划的一环</span><span>，</span><span>这些新装置在需要额外</span><span><span>&nbsp;</span>I/O<span>&nbsp;</span></span><span>时</span><span>，</span><span>为工程师提供简单的解决方案</span><span>，</span><span>同时保持最低程度的互连</span><span>，</span><span>例如在</span><span><span>&nbsp;</span>ADAS</span><span>、车载资通讯及信息娱乐方面。使用这些装置，无需使用外部电压电位转换器，可简化全新</span><span><span>&nbsp;</span>ADAS<span>&nbsp;</span></span><span>和车载资通讯系统的设计作业，也降低</span><span><span>&nbsp;</span>BOM<span>&nbsp;</span></span><span>成本。</span></p>

<p><span>这两款装置在</span><span><span>&nbsp;</span>GPIO<span>&nbsp;</span></span><span>端口侧的操作电压为</span><span><span>&nbsp;</span>1.65V<span>&nbsp;</span></span><span>至</span><span><span>&nbsp;</span>5.5V</span><span>。在</span><span><span>&nbsp;</span>SCL/SDA<span>&nbsp;</span></span><span>端</span><span><span>&nbsp;</span>(I2C<span>&nbsp;</span></span><span>接口</span><span>)</span><span>，</span><span>PI4IOE5V6416Q<span>&nbsp;</span></span><span>的操作电压为</span><span><span>&nbsp;</span>1.65V<span>&nbsp;</span></span><span>至</span><span><span>&nbsp;</span>5.5V</span><span>，</span><span>PI4IOE5V6534Q<span>&nbsp;</span></span><span>为</span><span><span>&nbsp;</span>0.8V<span>&nbsp;</span></span><span>至</span><span><span>&nbsp;</span>3.6V</span><span>。这种双电源轨允许装置在</span><span><span>&nbsp;</span>SCL/SDA<span>&nbsp;</span></span><span>端与新世代低功耗微芯片连接。扩充器的待机电流消耗极低，</span><span>PI4IOE5V6416Q<span>&nbsp;</span></span><span>在</span><span><span>&nbsp;</span>5V<span>&nbsp;</span></span><span>时为</span><span><span>&nbsp;</span>1.5μA</span><span>，在</span><span><span>&nbsp;</span>3.3V<span>&nbsp;</span></span><span>时为</span><span><span>&nbsp;</span>1μA</span><span>，</span><span>PI4IOE5V6434Q<span>&nbsp;</span></span><span>在</span><span><span>&nbsp;</span>3.3V<span>&nbsp;</span></span><span>时为</span><span><span>&nbsp;</span>2μA</span><span>。</span></p>

<p><span>这些装置上的每个</span><span><span>&nbsp;</span>16<span>&nbsp;</span></span><span>位或</span><span><span>&nbsp;</span>34<span>&nbsp;</span></span><span>位</span><span><span>&nbsp;</span>GPIO<span>&nbsp;</span></span><span>都是可设定</span><span>，</span><span>每个端口都有可编程的上拉或下拉电阻</span><span>，</span><span>以及可编程的输出电流。与许多</span><span><span>&nbsp;</span>I/O<span>&nbsp;</span></span><span>扩充器不同，</span><a href="https://www.diodes.com/part/PI4IOE5V6416Q"><span>PI4IOE5V6416Q</span></… href="https://www.diodes.com/part/PI4IOE5V6534Q"><span>PI4IOE5V6534Q</span></…，作为增强型</span><span><span>&nbsp;</span>I/O<span>&nbsp;</span></span><span>功能的一部分。这些装置具有中断屏蔽功能，让设计人员能够屏蔽来自单个</span><span><span>&nbsp;</span>GPIO<span>&nbsp;</span></span><span>端口的中断，并且启动系统层面的操作。</span></p>

<p><span>16<span>&nbsp;</span></span><span>位</span><span><span>&nbsp;</span>PI4IOE5V6416Q<span>&nbsp;</span></span><span>采用</span><span><span>&nbsp;</span>24<span>&nbsp;</span></span><span>接脚</span><span><span>&nbsp;</span>TSSOP<span>&nbsp;</span></span><span>封装</span><span>，</span><span>34<span>&nbsp;</span></span><span>位</span><span><span>&nbsp;</span>PI4IOE5V6534Q<span>&nbsp;</span></span><span>采用</span><span><span>&nbsp;</span>W-QFN4565-46<span>&nbsp;</span></span><span>封装。这两款装置皆由</span><span><span>&nbsp;</span>IATF 16949<span>&nbsp;</span></span><span>认证的设施制造</span><span>，</span><span>并支持</span><span><span>&nbsp;</span>PPAP<span>&nbsp;</span></span><span>文件。</span></p>
