USB5742T/2GX01

Controllers Overview

The USB5742T/2GX01 is a low-power, OEM-configurable USB 3.2 Gen 1 hub feature controller manufactured by Microchip Technology. It provides two downstream ports supporting SuperSpeed (5 Gbps), Hi-Speed (480 Mbps), Full-Speed (12 Mbps), and Low-Speed (1.5 Mbps) data rates. The device integrates an embedded 8051 microcontroller with 64 KB ROM, 8 KB RAM, and 8 KB OTP memory for firmware execution and configuration. It supports USB-IF Battery Charging revision 1.2 profiles including DCP, CDP, and SDP. The component is housed in a 56-pin VQFN package measuring 7 x 7 mm and operates within commercial (0°C to +70°C) and industrial (-40°C to +85°C) temperature ranges.

Controllers Feature Summary

• Supports USB 3.2 Gen 1 and USB 2.0 Link Power Management for optimized power efficiency.
• Includes PortSwap, PHYBoost, and VariSense features to enhance signal integrity and flexibility in PCB layout.
• Enables battery charging compliance through integrated detection circuitry for multiple industry standards.
• Allows flexible system configuration via internal OTP, external SPI ROM, or SMBus interfaces.

Controllers Applications

• Standalone USB Hubs
• Laptop Docks
• PC Motherboards
• Multi-function USB 3.2 Gen 1 Peripherals

Controllers Procurement Notes

Verify the specific suffix 'X01' against the official datasheet to confirm pinout and configuration options, as suffixes often denote packaging or regional variants. Check the current lifecycle status, as this series may be marked as Not Recommended for New Designs (NRND). Ensure compatibility with required operating temperatures and interface protocols before finalizing procurement.

Controllers Selection Notes

Select this component when a compact, dual-port USB hub solution with advanced signal integrity features is required. Consider the integrated battery charging capabilities if powering mobile devices. Evaluate the need for custom firmware storage via SPI ROM versus internal OTP based on production volume and update requirements. Verify that the 56-pin VQFN package fits the target board space constraints.

Controllers Part Context

The USB5742 belongs to the USB5742 family of USB hub controllers from Microchip Technology. This series is designed for embedded applications requiring high-speed data transfer and low power consumption. The T/2G suffix typically indicates specific packaging or testing configurations within the broader product line.

Controllers Replacement Considerations

Consult the manufacturer's documentation for officially confirmed substitute part numbers. Generic cross-references should be avoided due to potential differences in firmware, pinouts, and electrical characteristics.
