【经验】瑞萨超高速USB 3.0主机控制器UPD720201上电后无法识别pcie设备的问题分析
UPD720201作为瑞萨（RENESAS）一款超高速USB 3.0主机控制器，包括pcie高速总线和usb3.0总线，在硬件原理图和PCB上需要严格按照官方参考设计来设计。最近有客户在使用UPD720201碰到问题，现象如下：掉电时间长一些，上电能够正常识别pcie设备，但是重新上电的时候，就识别不了。本文将简要分析原因。
检查客户原理图发现复位电路如下图所示，可以计算出上电复位电路充电时间为1ms。
通过查看UPD720201的数据手册，最小充电时间为1ms。客户的复位电路刚好在临界点，建议客户将电阻值1K改成10K，保证充电时间足够长，客户修改成10K后，每次上电后都能正常识别到pcie设备。
总结：遇到不熟悉的数字芯片，需要尽量多参考官方资料和数据手册，可以减少一些不必要的问题出现。

主板与设备的转接卡项目中需要转5个USB2.0，原采用UPD720101GJ-UEN-A已停产，UPD720210可以代替吗？有没有PCI转USB 2.0的产品？
可以代替。UPD720101GJ-UEN-A是USB2.0，UPD720210是USB3.0兼容2.0。有可应用于PCI转USB 2.0的产品，最多是转4个USB2.0口。UPD720201/UPD720202是PCI-E转USB2.0，PCI-E可向下兼容PCI，相对于传统PCI总线在单一时间周期内只能实现单向传输，PCI-E的双单工连接能提供更高的传输速率和质量。UPD720114/UPD720115集线器方便进行USB口扩展，可用它实现转5个USB口。
