TUSB2046IBVFR

Controllers Overview

The TUSB2046IBVFR is a USB hub controller manufactured by Texas Instruments, designed for full-speed data transfer applications. It supports the USB 1.1 and USB 2.0 standards with a maximum data rate of 12 Mbps. The device features four downstream ports and operates within a supply voltage range of 3 V to 3.6 V, typically at 3.3 V, with a working power current of 40 mA. It is housed in a 32-LQFP package measuring 7x7 mm and is rated for an operating temperature range from -40°C to +85°C. The component includes an optional serial EEPROM interface and supports 6-MHz crystal or 48-MHz clock input.

Controllers Feature Summary

• Integrates four downstream ports for USB full-speed connectivity
• Supports connection to an external serial EEPROM for configuration storage
• Includes built-in ESD protection on all I/O lines
• Compatible with standard USB 1.1 and USB 2.0 protocols

Controllers Applications

• Peripheral expansion hubs for computing devices
• Industrial control systems requiring USB connectivity
• Embedded systems needing multiple USB device connections

Controllers Procurement Notes

Verify the specific suffix 'R' indicates reel packaging when ordering. Confirm the 'I' designation corresponds to the industrial temperature grade (-40°C to +85°C). Ensure compatibility with the target system's voltage levels and clock requirements before procurement. Check for moisture sensitivity level (MSL 3) handling requirements during storage and assembly.

Controllers Selection Notes

Select this component when a four-port full-speed hub solution is required in a LQFP-32 package. Compare against the TUSB2046B series if a VQFN package is preferred for space-constrained designs. Verify that the host controller supports the necessary serial interface for any optional EEPROM usage. Ensure the application environment falls within the specified industrial temperature range.

Controllers Part Context

This part belongs to the TUSB2046 family of USB hub controllers from Texas Instruments. It serves as a bridge between a USB host controller and multiple USB peripherals. The IBVFR variant specifically denotes the industrial temperature grade and LQFP-32 packaging with reel delivery. It is distinct from the B-series variants which may offer different package options like VQFN.

Controllers Replacement Considerations

TUSB2046BVFR offers the same electrical specifications but in the same LQFP-32 package with commercial temperature grade. TUSB2046BIRHBT provides equivalent functionality in a compact VQFN-32 package.
