USB2512B-AEZG-TR

Controllers Overview

The Microchip USB2512B-AEZG-TR is a USB 2.0 high-speed hub controller IC featuring two downstream ports and battery charging support. It operates on a single 3.3 V supply with an internal 1.2 V regulator, supporting data rates up to 480 Mb/s. The device utilizes MultiTRAK technology for dedicated transaction translators per port and includes integrated termination resistors. It supports self-powered or bus-powered operation, offers configurable vendor/product IDs via I2C/SMBus, and provides 4 kV HBM ESD protection.

Controllers Feature Summary

• MultiTRAK technology provides dedicated transaction translators for each port to maintain consistent full-speed throughput.
• PortMap allows flexible port mapping and disable sequencing for platform design optimization.
• PHYBoost enables programmable signal drive strength to recover signal integrity.
• Supports USB Battery Charging Specification Rev 1.1 for downstream ports.

Controllers Applications

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

Controllers Procurement Notes

Verify the specific suffix AEZG-TR against the official datasheet to confirm package type (36-pin SQFN) and temperature range (extended commercial). Ensure the source document matches the manufacturer's current revision DS00001692C. Confirm RoHS compliance status as stated in the product identification system.

Controllers Selection Notes

Select this component when a low-power, footprint-compatible USB 2.0 hub with two downstream ports is required. It serves as a direct drop-in replacement for legacy USB2512 variants. Consider the industrial temperature variant if operating conditions exceed the extended commercial range of 0°C to +85°C.

Controllers Part Context

This part belongs to the USB251xB/xBi family of multi-transaction translator hub controllers. The '2' indicates two downstream ports, while 'B' denotes battery charging support. These devices are designed for embedded USB solutions and offer enhanced OEM configuration options through serial interfaces.

Controllers Replacement Considerations

The USB2512B is fully footprint compatible with USB2512, USB2512i, USB2512A, and USB2512Ai products. These serve as direct drop-in replacements allowing the use of identical PCB components and facilitating USB-IF Compliance by Similarity.

Controllers FAQ

How is the battery charging feature enabled?

Battery charging can be enabled via pin strapping using the BC_EN pins or by configuring the corresponding bits via an external I2C EEPROM or SMBus interface.

What is the function of PortSwap?

PortSwap allows programmable USB differential-pair pin locations, easing PCB design by aligning USB signal lines directly to connectors to avoid uneven trace lengths.

Does the device require external termination resistors?

No, the USB2512B-AEZG-TR has fully integrated USB termination and pull-up/pull-down resistors for all downstream ports.
