USB2514B-AEZG-TR

Controllers Overview

The USB2514B-AEZG-TR is a Microchip Technology USB 2.0 high-speed hub controller IC featuring four downstream ports. It operates within a supply voltage range of 3 V to 3.6 V and supports data rates up to 480 Mb/s. The device utilizes a 36-pin QFN package measuring 6x6 mm. It supports self-powered or bus-powered operation, includes integrated power management for individual or ganged port control, and provides 4 kV HBM ESD protection. The component is designed for embedded USB solutions with MultiTRAK technology.

Controllers Feature Summary

• MultiTRAK technology implements a dedicated transaction translator per port to maintain consistent full-speed throughput.
• PortMap feature allows flexible port mapping and disable sequencing for platform design optimization.
• PortSwap enables programmable differential-pair pin locations to align signals directly to connectors.
• PHYBoost offers four programmable drive strength levels 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 the specific suffix 'AEZG' against the manufacturer's current documentation to confirm package type and temperature range. Ensure the ordering suffix matches the required RoHS compliance status and moisture sensitivity level. Confirm that the TR designation corresponds to the intended reel packaging format for surface mount assembly processes.

Controllers Selection Notes

Select this model when four downstream ports are required for USB 2.0 high-speed connectivity. Consider the USB2514Bi variant if an industrial temperature range of -40°C to +85°C is necessary instead of the commercial 0°C to +85°C range. Verify compatibility with existing PCB layouts as it is footprint compatible with previous USB251x family members.

Controllers Part Context

This component belongs to the USB251xB/xBi hub controller family from Microchip Technology. The 'B' suffix indicates support for battery charging specifications, while the '4' denotes four downstream ports. It serves as a direct drop-in replacement for legacy USB2514 products, maintaining pin compatibility and allowing cost savings through shared PCB components.

Controllers Replacement Considerations

The USB2514B is fully footprint compatible with the USB2514 as a direct drop-in replacement. It also maintains compatibility with other variants in the USB251x/xi/xA/xAi family, allowing for potential substitution without redesigning the printed circuit board layout.

Controllers FAQ

How does the USB2514B handle battery charging?

It supports the USB Battery Charging Specification Rev. 1.1 for Charging Downstream Ports (CDP), enabling devices to draw higher currents on VBUS even when the hub is not enumerated.

What configuration methods are supported?

The device can be configured via strapping options at reset or through an external I2C EEPROM or SMBus slave interface for enhanced OEM customization.

Is the USB2514B compatible with older USB2514 designs?

Yes, it is fully footprint compatible with USB251x/xi/xA/xAi products, serving as a direct drop-in replacement that uses the same PCB components.
