USB2513I-AEZG

Controllers Overview

The USB2513I-AEZG is a low-power, OEM-configurable USB 2.0 Hi-Speed hub controller IC from the SMSC USB251x family. It features three downstream ports and utilizes MultiTRAK technology to provide one transaction translator per port for high-performance data throughput. The device supports low-speed, full-speed, and hi-speed downstream devices on all enabled ports. It operates within an industrial temperature range of -40°C to +85°C and is housed in a 36-pin QFN package measuring 6x6 mm with a height of 0.5 mm.

Controllers Feature Summary

• MultiTRAK technology provides dedicated transaction translators per port to maintain consistent full-speed data throughput regardless of active downstream connections.
• PortMap allows flexible port mapping and disable sequencing to support multiple platform designs with minimal effort.
• PortSwap enables programmable USB differential-pair pin locations to align signals directly to connectors and simplify PCB design.
• PHYBoost offers four programmable levels of USB signal drive strength to restore signal integrity.

Controllers Applications

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

Controllers Procurement Notes

Verify the specific ordering suffix 'I' confirms the industrial temperature range (-40°C to +85°C) as documented in the datasheet's order numbers table. Ensure the component matches the 36-pin QFN package specifications. Confirm RoHS compliance status through official manufacturer documentation prior to integration into production designs.

Controllers Selection Notes

Select this component for embedded USB solutions requiring three downstream ports with high-performance multi-transaction translation capabilities. Consider the USB2513B variant if an extended commercial temperature range (0°C to +85°C) suffices for the application environment. Evaluate the need for SMBus or I2C EEPROM configuration options based on system architecture requirements.

Controllers Part Context

This part belongs to the SMSC USB251x hub family, which includes variants with two, three, four, or seven downstream ports. The 'I' suffix denotes the industrial temperature grade, distinguishing it from standard commercial versions. The family is designed for low power consumption and small footprint applications, offering full compliance with USB 2.0 specifications.

Controllers Replacement Considerations

USB2513B-AEZG serves as a direct drop-in replacement with identical footprint compatibility. Both parts utilize the same PCB components and allow for USB-IF Compliance by Similarity. Verify that register defaults and PID/DID configurations are adjusted to match the target application requirements when substituting between these variants.
