USB 2.0 compliant transceivers are integrated for upstream and all downstream ports. The μPD720114 works backward compatible either when any one of the downstream ports is connected to a USB 1.1 compliant device, or when the upstream port is connected to a USB 1.1 compliant host. Mbps) transaction. ? Supports split transaction to handle full-speed and low-speed transaction on downstream facing ports when Hub controller is working in high-speed mode. ? One Transaction Translator per Hub and supports four non-periodic buffers ? Supports self-powered and bus-powered mode ? Supports individual or global over-current detection and individual or ganged power control ? Supports downstream port status with LED ? Supports non-removable devices by I/O pin configuration ? Support Energy Star for PC peripheral system ? On chip Rpu, Rpd resistors and regulator (for core logic) ? Use 30 MHz crystal ? 3.3 V power supply
