新款USB 3.0控制器采用了QFN小尺寸封装，UPD720201封装尺寸8x8mm，UPD720202封装尺寸7x7mm，相比上代产品缩小50%。新款芯片还支持从BIOS通过PCI-E总线下载安装固件升级，不再需要搭配外置闪存，降低了整个解决方案的PCB面积和芯片数量。瑞萨有效降低了芯片工作在低功耗状态（未连接USB外设）的漏电流水平，从而将低功耗状态功率降至4.5mW，相比上代产品节电90%。通过改善数据传送处理电路，使用外置硬盘等USB 3.0设备的实际传输速度相比上代µPD720200A可提升40%。新品UPD720201可提供4个USB 3.0接口，UPD720202则为2个。 Feature
