USB2533-1080AEN-TR

Controllers Overview

The USB2533-1080AEN-TR is a low-power, OEM configurable USB 2.0 hub controller featuring three downstream ports and one upstream port within a 36-pin SQFN package. It supports Hi-Speed data transfer at 480 Mbps and complies with the USB 2.0 Specification and Link Power Management Addendum. The device integrates dedicated Transaction Translators per port for consistent Full-Speed throughput. It includes built-in battery charger detection supporting USB-IF BC1.2 profiles (DCP, CDP, SDP) and Apple devices. Configuration options include I2C EEPROM, OTP, or SMBus Slave Port. Internal regulators provide 3.3V and 1.2V supplies, and it operates in commercial temperature ranges.

Controllers Feature Summary

• MultiTRAK technology provides a dedicated Transaction Translator per downstream port to maintain consistent Full-Speed data throughput regardless of active connections.
• FlexConnect allows Downstream Port 1 to swap with the Upstream Port, enabling master-capable devices to control other hub devices.
• Integrated Battery Charger Detection circuitry supports USB-IF BC1.2 standards and Apple device charging protocols via DCP, CDP, and SDP profiles.
• PortMap and PortSwap features enable configurable port mapping, disable sequencing, and differential intra-pair signal swapping for optimized PCB layout.

Controllers Applications

• LCD monitors and televisions
• Multi-function USB peripherals
• PC motherboards
• Set-top boxes, DVD players, and DVR/PVR systems
• Printers and scanners

Controllers Procurement Notes

Verify the specific ordering suffix against the manufacturer's current documentation to ensure correct packaging and temperature grade. Confirm that the required configuration method, such as external EEPROM or OTP programming, aligns with the selected variant. Check for any recent Product Change Notifications regarding assembly sites or material updates before finalizing procurement orders.

Controllers Selection Notes

Select this component when a compact USB 2.0 hub solution with three downstream ports is required for embedded designs. Ensure the design accommodates the 36-SQFN footprint and utilizes the integrated internal voltage regulators. Consider the FlexConnect feature if system architecture requires swapping the upstream connection with a downstream port for master control capabilities.

Controllers Part Context

This part belongs to the Microchip USB253x series of USB 2.0 hub controllers. It shares functional similarities with the USB2532 but offers an additional downstream port. The device is designed to replace legacy hub controllers while providing enhanced configuration flexibility through serial interfaces and improved power management features for modern embedded applications.

Controllers Replacement Considerations

The USB2533B is a compatible alternative within the same family offering similar functionality. Verify pin compatibility and configuration strap requirements when substituting between variants. Ensure that the replacement part supports the specific battery charging profiles and temperature range required by the target application.
