TUSB2036VFRG4

Controllers Overview

The TUSB2036VFRG4 is a 2- or 3-port Universal Serial Bus (USB) hub controller manufactured by Texas Instruments. It supports USB 2.0 Full-Speed and Low-Speed devices, enabling connection of multiple peripherals to a single host port. The device integrates an optional serial EEPROM interface for storing configuration data. It operates within a supply voltage range of 3.0 V to 5.5 V and is housed in a 32-pin LQFP package with a 0.5 mm pitch. The controller includes overcurrent protection and power switching capabilities for downstream ports.

Controllers Feature Summary

• Supports connection of low-speed USB devices to full-speed only hosts via internal protocol translation
• Integrates configurable serial EEPROM interface for persistent device identification storage
• Provides independent overcurrent detection and power switching for each downstream port

Controllers Applications

• Connecting low-speed input devices such as keyboards and mice to full-speed USB host controllers
• Expanding connectivity for embedded systems requiring multiple USB peripherals
• Industrial control panels needing robust USB hub functionality with EEPROM-based configuration

Controllers Procurement Notes

Verify the specific suffix RG4 indicates the LQFP32 package variant when sourcing. Confirm that the component meets RoHS compliance requirements if applicable to your manufacturing standards. Ensure the supplier provides traceability documentation consistent with original equipment manufacturer specifications for quality assurance purposes.

Controllers Selection Notes

Select this component when interfacing low-speed USB peripherals with full-speed hosts is required. Consider the integrated EEPROM feature if system configuration persistence is necessary without external memory components. Evaluate the LQFP32 package constraints against available PCB real estate and thermal management capabilities during the design phase.

Controllers Part Context

This part belongs to the TUSB2036 family of USB hub controllers from Texas Instruments. It serves as a bridge between high-speed hosts and low-speed peripherals, addressing compatibility gaps in embedded designs. The VFRG4 designation specifies the tape-and-reel packaging format and the specific lead-free LQFP32 enclosure used for surface-mount assembly.

Controllers Replacement Considerations

Direct substitutes include other TUSB2036 variants with different package options such as TUSB2036VF. For expanded port counts, consider the TUSB2040A series. Verify pinout compatibility and software configuration differences before implementing any cross-model replacements in existing designs.
