µPD720110A
USB2.0 HUB CONTROLLER
The µPD720110A is an USB 2.0 hub device that comply with the Universal Serial Bus (USB) Specification Revision
2.0 and work up to 480 Mbps. USB2.0 compliant transceivers are integrated for upstream and all downstream ports.
The µPD720110A works backward compatible either when any one of downstream ports is connected to an 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.
µPD720110A User’s Manual: S15738E
FEATURES
• Compliant with Universal Serial Bus Specification Revision 2.0 (Data Rate 1.5/12/480 Mbps)
• Certified by USB implementers forum and granted with 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 at downstream facing ports when Hub
controller is working at high-speed mode.
• One Transaction Translator per Hub and supports 4 non-periodic buffers
• Supports self-powered mode only
• Supports Over-current detection and Individual power control
• Supports configurable vendor ID and product ID with external Serial ROM
• Supports “non-removable” attribution on individual port
• Uses 30 MHz X’tal, 30 MHz clock input, or 48 MHz clock input
• Supports downstream port status with LED
• HS detection indicator output
• 3.3 V power supply

: Generates all clocks of Hub.
: Translates the high-speed transactions (split transactions) for full/low-speed device
to full/low-speed transactions. ALL_TT buffers the data transfer from either
upstream or downstream direction. For OUT transaction, ALL_TT buffers data from
upstream port and sends it out to the downstream facing ports after speed
conversion from high-speed to full/low-speed. For IN transaction, ALL_TT buffers
data from downstream ports and sends it out to the upstream facing ports after
speed conversion from full/low-speed to high-speed.
: Data & clock recovery circuit
: Downstream Port Controller handles Port Reset, Enable, Disable, Suspend and
Resume
: Downstream transceiver supports high-speed (480 Mbps), full-speed (12 Mbps), and
low-speed (1.5 Mbps) transaction
: Endpoint 0 controller
: Endpoint 1 controller
: Manages hub’s synchronization by using micro-SOF which is received at upstream
port, and generates SOF packet when full/low-speed device is attached to
downstream facing port.
: Full/low-speed repeater is enabled when the µPD720110A is worked at full-speed
mode
: Oscillator Block
: Contains default Descriptors
: Interface block for external Serial ROM which contains user-defined Descriptors
: Serializer and Deserializer
: Serial Interface Engine (SIE) controls USB2.0 and 1.1 protocol sequencer
: Upstream Transceiver supports high-speed (480 Mbps), full-speed (12 Mbps)
transaction
: Upstream Port Controller handles Suspend and Resume
