USB5537B-6080AKZETR

Controllers Overview

The USB5537B-6080AKZETR 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, operating in parallel to prevent bandwidth contention. It features an embedded 8051 microcontroller with 8 KB RAM and 32 KB ROM, supporting configuration via OTP ROM, SPI ROM, or SMBus. The -6080 variant includes Dynamic Charging Port support and non-removable USB 2.0 port defaults.

Controllers Feature Summary

• Parallel operation of SuperSpeed and Hi-Speed controllers for uninterrupted high-bandwidth transfers
• Integrated battery charging emulation for CDP, DCP, and proprietary protocols
• Configurable port power control and over-current detection on individual or ganged bases
• On-chip 8051 microcontroller managing VBUS and hub signals with firmware upload capability

Controllers Applications

• High-performance docking stations requiring simultaneous USB 3.0 and USB 2.0 connectivity
• Industrial and commercial kiosks needing reliable peripheral expansion
• Portable devices requiring fast charging emulation from mobile platforms
• Embedded systems integrating multiple USB peripherals with low-power constraints

Controllers Procurement Notes

Verify the specific -6080 silicon revision to ensure compatibility with required dynamic charging features and default port configurations. Confirm that the QFN-72 package footprint matches the target PCB layout. Check for any applicable errata sheets related to the document revision DS00001682C before finalizing design integration.

Controllers Selection Notes

Select this model when seven downstream ports are required with four dedicated SuperSpeed lanes. The -6080 version is appropriate if non-removable USB 2.0 ports are preferred by default. Ensure the design accommodates the 72-pin QFN package and provides adequate thermal dissipation for low-power operation.

Controllers Part Context

This component belongs to the USB5537B family of hub controllers. It serves as a bridge between host systems and multiple USB peripherals. The -6080 suffix denotes a specific silicon revision with enhanced charging capabilities and distinct default port behaviors compared to other variants like the -5000 or -6070.

Controllers Replacement Considerations

Direct substitutes within the same family include the USB5537B-5000 and USB5537B-6070. Note that these alternatives differ in dynamic charging support, pin buffer types, and default port removability settings. Verify functional equivalence against specific application requirements before substitution.

Controllers FAQ

What is the difference between the USB5537B-6080 and -6070 revisions?

The -6080 revision defaults the three USB 2.0 ports as non-removable, whereas the -6070 defaults them as removable. Both versions support Dynamic Charging Ports and have IPU buffer types for the TRST/DYNCPDIS_N pin.

How does the USB5537B handle SuperSpeed and Hi-Speed traffic?

The SuperSpeed hub controller operates in parallel with the USB 2.0 hub controller. This architecture ensures that 5 Gbps SuperSpeed data transfers are not affected by slower USB 2.0 traffic on the same hub.

Can the USB5537B emulate wall chargers for fast charging?

Yes, it supports USB-IF Battery Charging rev. 1.2 (DCP & CDP) and emulates Apple, Blackberry, and Chinese YD/T standards to enable fast charging for portable devices.
