USB2512AI-AEZG

Controllers Overview

The USB2512AI-AEZG is a low-power, OEM-configurable USB 2.0 Hi-Speed hub controller featuring two downstream ports. It utilizes a single transaction translator and supports Low-Speed, Full-Speed, and Hi-Speed devices. The device operates within an industrial temperature range of -40°C to +85°C and accepts a single external 3.3V supply, utilizing internal regulators for core voltage. Configuration is achieved via I2C EEPROM or SMBus interface, allowing customization of Vendor ID, Product ID, and Device ID. It includes integrated termination resistors, programmable drive strength (PHYBoost), and differential pair pin swapping (PortSwap) to simplify PCB layout.

Controllers Feature Summary

• Supports flexible port mapping and disable sequencing through PortMap technology
• Provides programmable USB signal drive strength levels to recover signal integrity via PHYBoost
• Enables direct alignment of USB signals to connectors using programmable differential-pair pin locations with PortSwap
• Allows enhanced OEM configuration options through serial I2C EEPROM or SMBus slave port

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 against the manufacturer's current datasheet to confirm package type and temperature range specifications. Ensure compatibility with the intended host system's power requirements and configuration interface before finalizing procurement orders.

Controllers Selection Notes

Select this component for designs requiring a compact 36-pin QFN footprint with industrial temperature ratings. Consider the single transaction translator limitation compared to MultiTRAK models when evaluating full-speed throughput requirements for mixed-speed device environments.

Controllers Part Context

This part belongs to the SMSC USB251x family of hub controllers, which are now manufactured by Microchip Technology following its acquisition of Standard Microsystems Corporation. The 'A' designation indicates commercial temperature variants in some contexts, but the 'Ai' suffix specifically denotes the industrial temperature range extension for this specific model.

Controllers Replacement Considerations

USB2512B-AEZG serves as a direct drop-in replacement with identical pinout and footprint compatibility. Verify that the B-series battery charging capabilities align with design requirements if CDP support is needed.

Controllers FAQ

Does the USB2512AI-AEZG use a multi-transaction translator?

No, the USB2512A and USB2512Ai models utilize a single transaction translator, whereas other parts in the USB251x family use MultiTRAK technology.

What is the operating temperature range for the USB2512AI-AEZG?

The USB2512Ai product supports the industrial temperature range of -40ºC to +85ºC.

How is the device configured after reset?

Configuration can be performed via an external I2C EEPROM or an SMBus slave interface connected to a microcontroller or host system.
