Overview

The USB2514B-AEZC-TR is a low-power, full-featured USB 2.0 Hi-Speed hub controller designed for embedded applications requiring four downstream ports. It integrates Microchips MultiTRAK technology, which utilizes a dedicated Transaction Translator for each port to ensure maximum throughput even when mixing high-speed and full-speed devices. The controller supports configuration via internal default settings, I2C, or SMBus for advanced customization.

Why Choose This Part

This controller offers a small 6x6mm footprint and high efficiency with a base supply current of 70mA. Its support for the USB 2.0 specification includes robust Battery Charging 1.1 support on downstream ports, allowing for faster charging of mobile devices. The flexibility of using I2C/SMBus for configuration allows engineers to modify Vendor IDs and port behaviors without an external EEPROM.

Applications

Industrial PC Peripherals
Expanding internal USB connectivity for touchscreens, wireless modules, and diagnostic ports in industrial computing environments.
Docking Stations
Providing reliable high-speed data multiplexing for port replicators and desktop docking solutions.
Embedded Single Board Computers
Adding integrated USB port expansion to SBCs where board space is limited but high-speed data transfer is required.
Gaming Consoles and Media Players
Managing multiple peripheral connections such as controllers and external storage through a single host interface.

Getting Started

Designers should refer to the Microchip EVB-USB2514B evaluation board for rapid prototyping and circuit verification. When layouting the 36-QFN package, ensure the central thermal pad is properly grounded to the PCB for heat dissipation and signal integrity. Configuration can be managed through pin-strapping for default operation or via an external microcontroller over the SMBus interface.
