DATA SHEET MOS INTEGRATED CIRCUIT μPD720114 ECOUSBTM Series USB 2.0 HUB CONTROLLER The μPD720114 is a USB 2.0 hub device that complies with the Universal Serial Bus (USB) Specification Revision 2.0 and works up to 480 Mbps. 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. Detailed function descriptions are provided in the following user’s manual. Be sure to read the manual before designing. μPD720114 User’s Manual: S17463E FEATURES • Compliant with Universal Serial Bus Specification Revision 2.0 (Data Rate 1.5/12/480 Mbps) • High-speed or full-speed packet protocol sequencer for Endpoint 0/1 • 4 (Max.) downstream facing ports • Low power consumption (10 μA when hub in idle status, 149 mA when all parts run in HS mode) • All downstream facing ports can handle high-speed (480 Mbps), full-speed (12 Mbps), and low-speed (1.5 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 The information in this document is subject to change without notice.
