The TUSB2043VFR is a 4-port USB hub compliant with the USB 1.1 specification, designed to provide one upstream and four downstream ports. It operates at a voltage of 3.3 V and features integrated USB transceivers, eliminating the need for firmware programming due to its digital state machine implementation. The hub supports both full-speed and low-speed operations on all downstream ports, automatically adjusting the slew rate based on the connected device. This device can be configured for either self-powered or bus-powered modes, with power management capabilities that include ganged or per-port over-current reporting. The TUSB2043VFR also supports an optional serial EEPROM interface for programmable vendor and product IDs, allowing for customization during device enumeration. Its 32-pin TQFP package facilitates easy PCB routing and assembly, while push-pull outputs for power control reduce the need for external pull-up resistors. The product is a cost-effective alternative to the TUSB2040 hub, making it suitable for various USB applications.
