USB5537B-6080AKZE

Controllers Overview

The USB5537B-6080AKZE is a 7-port SuperSpeed/Hi-Speed configurable hub controller compliant with the USB 3.0 Specification. It supports data rates of 5 Gbps (SuperSpeed), 480 Mbps (Hi-Speed), 12 Mbps (Full-Speed), and 1.5 Mbps (Low-Speed). The device integrates four downstream USB 3.0 ports and three additional USB 2.0 ports. It features an embedded 8051 microcontroller, 8 KB RAM, 32 KB ROM, and 8 kbit OTP ROM. Configuration is supported via internal defaults, on-chip OTP ROM, external SPI ROM, or SMBus. The component operates with single 25 MHz XTAL or clock input and includes integrated terminations and pull-up/pull-down resistors.

Controllers Feature Summary

• Supports simultaneous operation of SuperSpeed and Hi-Speed controllers to prevent traffic interference
• Enables per-port battery charging with emulation for various portable device standards
• Includes programmable signal integrity features such as PHYBoost and VariSense
• Configurable port power control and over-current detection on individual or ganged basis

Controllers Applications

• Desktop docking stations requiring multiple high-speed peripheral connections
• Industrial equipment interfaces needing robust USB connectivity
• Consumer electronics hubs supporting fast charging protocols

Controllers Procurement Notes

Verify silicon revision compatibility during sourcing. Confirm that the -6080 firmware variant matches system requirements for dynamic charging port support and default removable port configuration. Ensure external SPI flash signatures align with boot sequence expectations if using external configuration storage.

Controllers Selection Notes

Select this model when seven total downstream ports are required with four dedicated SuperSpeed lanes. Verify that the application utilizes the -6080 specific features such as lowered global suspend power consumption and dynamic charging capabilities. Ensure PCB layout accommodates the 72-pin QFN package and ground pad via field requirements.

Controllers Part Context

This component belongs to the USB5537B family of hub controllers. The -6080 suffix indicates a specific firmware version offering dynamic charging port functionality and distinct default port configurations compared to other variants like the -5000 or -6070. It serves as a central interface solution for expanding USB connectivity in host systems.

Controllers Replacement Considerations

Direct functional substitutes within the same family include the USB5537B-5000 and USB5537B-6070. Note differences in dynamic charging support, pin buffer types, and default port removability settings between these firmware revisions before substitution.
