Overview

The TUSB2046IBVF is a 4-port USB 1.1 compliant hub controller designed for low-cost, high-reliability implementations. It utilizes a hardware state machine approach, eliminating the need for firmware programming and simplifying the design process for embedded USB expansion.

Why Choose This Part

The device operates without external firmware, reducing development time and complexity. It features a low 40mA run current and a highly efficient 1uA sleep mode, while the 32-LQFP package is optimized for 2-layer PCB layouts to keep manufacturing costs low.

Applications

Industrial Control Panels
Adding multiple USB human interface devices (HID) to a single industrial PLC or computer port.
Embedded Computing Hubs
Expanding internal USB connectivity for peripherals like WiFi modules, cellular modems, and touch controllers.
Diagnostic Tools
Creating multi-port test interfaces for production environments requiring simultaneous device monitoring.

Getting Started

Designers should provide a 6-MHz crystal or 48-MHz clock input for operation. While it functions as a stand-alone hub, an optional external serial EEPROM can be used via the 3-state interface to customize Vendor and Product IDs (VID/PID).
