【选型】国产GPIO扩展芯片XL9555 PTP替换PCA9555APW，助力服务器主板控制总线设计
随着物联网等应用的持续发展，系统设计的复杂度不断增加，主设备和许多终端设备共存于同一系统中，增加了控制总线布局难度，往往需要GPIO扩展芯片来简化电路设计和提高信号完整性，最终降低系统总成本。某客户服务器主板中采用了NXP的接口芯片PCA9555APW作为外设的控制和状态监测，由于国产化要求，需求替代物料，本文重点推荐国产信路达的XL9555，下面从二者性能参数等方面对比分析替代可行性。
图1 XL9555和PCA9555APW性能参数对比图
由上图对比可知：
1、 PCA9555APW具有更宽输入电压范围，但实际应用中3.3V和5V供电居多，XL9555完全可以满足输入电压要求。
2、 在其它性能和参数方面，XL9555和PCA9555APW表现一致，可以替代。
3、 XL9555和PCA9555APW的封装均为TSSOP24，其Pin脚定义及分布如下图。
图2 XL9555和PCA9555APW的Pin脚定义及分布图
从上图可知：XL9555和PCA9555APW的Pin脚定义及分布完全相同，可以完美实现Pin -to-Pin兼容替换，在电路设计时无需改版，大大减小测试验证过程，加快项目进度。
