TUSB2036VFR Datasheet

2- or 3-Port Hub for the Universal Serial Bus With Optional Serial EEPROM Interface


The TUSB2036 hub is a 3.3-V CMOS device that provides up to three downstream ports in compliance with the USB 2.0 specification. Because this device is implemented with a digital state machine instead of a microcontroller, no firmware programming is required.
Fully-compliant USB transceivers are integrated into the ASIC for all upstream and downstream ports.

• One Upstream Port and 2 or 3 Programmable Downstream Ports
   – Total Number of Ports (2 or 3) Selected by Input Pin
   – Total Number of Permanently Connected Ports Is Selected by 2 Input Pins
• Two Power Source Modes
   – Self-Powered Mode
   – Bus-Powered Mode
• All Downstream Ports Support Full-Speed and Low-Speed Operations
• Power Switching and Overcurrent Reporting Is Provided Ganged or Per Port
• Supports Suspend and Resume Operations
• Suspend Status Pin Available for External Logic Power Down
• Supports Custom Vendor ID and Product ID With External Serial EEPROM
• 3-State EEPROM Interface Allows EEPROM Sharing
• Push-Pull Outputs for PWRON Eliminate the Need for External Pullup Resistors
