USB2532I-1080AEN

Controllers Overview

The USB2532I-1080AEN is a low-power, OEM configurable USB 2.0 hub controller featuring two downstream ports and one upstream port within a 36-pin SQFN package. It supports Hi-Speed data transfer at 480 Mbps and Full-Speed operation. The device integrates battery charger detection compliant with USB-IF BC1.2 standards, including support for Apple devices. Key architectural features include MultiTRAK technology with dedicated transaction translators per port, FlexConnect for port swapping, and programmable PHY settings via PHYBoost and VariSense. Configuration is managed through I2C/SMBus interfaces or One-Time Programmable memory.

Controllers Feature Summary

• MultiTRAK Technology provides dedicated transaction translators for each downstream port to maintain consistent full-speed throughput regardless of active connection counts.
• FlexConnect allows the upstream port to be swapped with downstream port 1, enabling master-capable devices to control other peripherals on the hub.
• Integrated battery charger detection circuitry supports USB-IF Battery Charging Specification Revision 1.2 profiles, including DCP, CDP, SDP, and custom profiles.
• Programmable signal integrity features include PHYBoost for adjustable drive strength and VariSense for receiver sensitivity tuning.

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 suffix 'I' indicates the industrial temperature range variant (-40°C to +85°C) as opposed to the commercial grade. Confirm the ordering suffix '1080AEN' corresponds to the correct packaging and configuration options required for the target design. Cross-reference the latest datasheet revision to ensure compatibility with current manufacturing processes and pin assignments.

Controllers Selection Notes

Select this component when embedded designs require high-performance full-speed data transfer with minimal bill-of-materials costs. The integrated power regulators and termination resistors simplify schematic design. Ensure the application benefits from the dedicated transaction translators if multiple low/full-speed devices are connected simultaneously. Verify that the 36-SQFN footprint aligns with the PCB layout constraints.

Controllers Part Context

This part belongs to the Microchip USB253x family of USB 2.0 hub controllers. It shares functional similarities with the USB2512B regarding footprint compatibility but offers enhanced configuration flexibility and performance features like MultiTRAK. The 'I' designation distinguishes it from commercial variants by extending the operating temperature range for more demanding environmental conditions.

Controllers Replacement Considerations

The USB2532B is a related variant within the same family. Check datasheet errata for silicon revisions. Footprint compatibility with USB2512B should be verified against specific pinout differences in the latest documentation before substitution.
