USB7056-I/KDX

Controllers Overview

The USB7056-I/KDX is a Microchip Technology USB hub controller supporting USB 3.2 Gen1 specifications with a data rate of 5 Gb/s. It features six downstream ports, comprising five Type-A and one native Type-C port with Power Delivery upstream support. The device operates within a supply voltage range of 1.2 V to 3.6 V and functions in temperatures from -40°C to +85°C. Packaged in a 100-pin VQFN (12mm x 12mm) format, it integrates GPIO bridge capabilities and supports I2C, SPI, and UART interfaces for flexible system integration.

Controllers Feature Summary

• Native Type-C upstream connectivity with integrated Power Delivery management
• Hybrid port configuration combining standard Type-A and modern Type-C downstream connections
• Integrated Hub Feature Controller enabling host-to-peripheral communication via I/O bridging
• Support for FlexConnect technology allowing dynamic role switching between upstream and downstream

Controllers Applications

• Embedded systems requiring mixed legacy and modern USB connectivity
• Industrial control panels needing robust I/O bridging capabilities
• Portable devices utilizing native Type-C charging and data transfer
• IoT gateways integrating multiple peripheral devices through a single host link

Controllers Procurement Notes

Verify component authenticity through authorized Microchip distributors or certified partners. Confirm the specific suffix matches the required package and temperature grade. Request official datasheets and RoHS compliance documentation prior to acquisition. Ensure storage conditions adhere to moisture sensitivity level requirements to prevent damage during assembly.

Controllers Selection Notes

Select this model when a combination of five traditional Type-A ports and one advanced Type-C port is necessary. Consider the integrated PD controller if direct Type-C power negotiation is required without external components. Evaluate the VQFN-100 footprint against available PCB space. Verify that the 5 Gb/s speed meets the bandwidth demands of connected peripherals.

Controllers Part Context

This component belongs to the USB70xx series of smart hubs designed by Microchip Technology. These controllers are engineered for OEM customization and low-power embedded applications. The series emphasizes flexibility through configurable I/O bridges and support for various operating systems including Windows, Linux, and macOS.

Controllers Replacement Considerations

The USB7056/KDX is listed as obsolete. Potential alternatives include the USB7052N-I/KDX for configurations with fewer downstream ports or the USB7016-KDX for similar functionality with different port arrangements. Verify pin compatibility and software driver support before substituting.
