MOS INTEGRATED CIRCUIT
µPD720112
USB 2.0 HUB CONTROLLER
The µPD720112 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 µPD720112 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.
µPD720112 User’s Manual: S16617E
FEATURES
• Compliant with Universal Serial Bus Specification Revision 2.0 (Data Rate 1.5/12/480 Mbps)
• Certified by USB implementers forum and granted the USB 2.0 high-speed Logo
• High-speed or full-speed packet protocol sequencer for Endpoint 0/1
• 4 (Max.) downstream facing ports
• 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 Over-current detection and Individual or ganged power control
• Supports configurable vendor ID, product ID, string descriptors and others with external Serial ROM
• Supports “non-removable” attribution on individual port
• Uses 30 MHz X’tal, or clock input
• Supports downstream port status with LED
• 2.5 V and 3.3 V power supplies
