USB2512A-AEZG-TR

Controllers Overview

The USB2512A-AEZG-TR is a low-power, OEM-configurable USB 2.0 Hi-Speed hub controller IC from the SMSC USB251x family. It features two downstream ports and operates within a commercial temperature range of 0°C to 70°C. The device supports Low-Speed, Full-Speed, and Hi-Speed downstream devices on all enabled ports. It utilizes a single transaction translator for data handling. Configuration options are available via an external serial I²C EEPROM or an SMBus slave port. The component includes fully integrated USB termination and pull-up/pull-down resistors, supporting both self-powered and bus-powered operations.

Controllers Feature Summary

• MultiTRAK technology provides dedicated transaction translation per port to maintain consistent full-speed data throughput.
• PortMap allows flexible port mapping and disable sequencing to support multiple platform designs.
• PortSwap enables programmable USB differential-pair pin locations to simplify PCB layout.
• PHYBoost offers four levels of programmable signal drive strength to recover 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 that the specific ordering suffix matches the required package type and temperature range. Confirm the presence of the 'A' designation in the part number to ensure the correct revision with single transaction translator functionality. Check RoHS compliance status against current manufacturing standards. Ensure the source document aligns with the official SMSC datasheet specifications before finalizing procurement orders.

Controllers Selection Notes

Select this component when a two-port USB 2.0 solution is required with OEM configurability. The USB2512A variant is distinct due to its use of a single transaction translator compared to other family members. Verify compatibility with the host system's power requirements for either self-powered or bus-powered operation. Consider the 36-pin QFN package dimensions for PCB footprint constraints.

Controllers Part Context

This component belongs to the SMSC USB251x Hub Family, which includes variants with different port counts and temperature ranges. The USB2512A specifically denotes a two-port controller with commercial temperature ratings. It is designed as a drop-in replacement for certain legacy controllers while offering enhanced configuration capabilities through external memory interfaces.

Controllers Replacement Considerations

The USB2512B serves as a direct drop-in replacement for the USB2512A, maintaining full footprint compatibility. Both parts utilize the same 36-pin QFN package and share identical pinouts. Designers can migrate between these models without altering the PCB layout or surrounding components.

Controllers FAQ

How many transaction translators does the USB2512A utilize?

The USB2512A uses a single transaction translator, unlike other members of the USB251x family which typically employ MultiTRAK technology with one translator per port.

What is the operating temperature range for the USB2512A-AEZG-TR?

The USB2512A-AEZG-TR operates within a commercial temperature range of 0°C to 70°C.

Can the USB2512A be configured via a microcontroller?

Yes, the hub can be configured by a microcontroller acting as an SMBus master, appearing as an SMBus slave device to the hub controller.
