The TUSB2046BVFR from Texas Instruments is a 3.3V CMOS hub device designed for Universal Serial Bus (USB) applications. It provides one upstream port and four downstream ports, fully compliant with the USB specification as a full-speed hub.
This controller features integrated USB transceivers and a state machine implementation that requires no firmware programming. It supports both full-speed and low-speed devices on its downstream ports, automatically adjusting slew rates. The device offers two power source modes: self-powered and bus-powered, with configurable power switching and overcurrent reporting.
Key features include support for suspend and resume operations, programmable Vendor ID and Product ID via an external serial EEPROM, and a 3-state EEPROM interface for sharing. The TUSB2046BVFR is housed in a 32-terminal LQFP package with a 0.8-mm terminal pitch and operates within a temperature range of 0°C to 70°C. Its design allows for 2-layer PCB implementation and achieves low EMI emissions using a 6-MHz crystal input.
This hub controller is designed for seamless integration with any operating system with USB stack support, requiring no special drivers. It is a cost-effective solution migrated from the proven TUSB2040 hub, offering enhanced system ESD performance.
