Overview

The USB2514B-AEZC is a high-performance, low-power USB 2.0 Hi-Speed hub controller offering four downstream ports. It is designed to provide high-speed data transfer and robust connectivity for embedded systems requiring a compact 36-pin QFN footprint. The controller operates from a 3V to 3.6V supply and includes internal power management features to minimize power consumption in both active and sleep modes.

Why Choose This Part

This controller features MultiTRAK technology for efficient data handling and supports customization via I2C or SMBus interfaces. It is highly power-efficient, drawing only 70mA during Hi-Speed host operations and dropping to 1200uA in sleep mode. The 36-VFQFN package with an exposed pad ensures excellent thermal performance and a small PCB footprint.

Applications

Industrial PC Expansion
Providing additional USB connectivity for single-board computers and industrial motherboards.
Embedded Systems Docking
Integration into docking stations for mobile devices or handheld instrumentation.
Automotive Infotainment
Routing multiple USB connections for media and charging interfaces within vehicle cabins.
Consumer Electronics
Expanding port availability in monitors, printers, and set-top boxes.

Getting Started

For rapid development, use the EVB-USB2514 evaluation board to test port connectivity and power delivery. Configure the hub's internal registers using an external I2C EEPROM or a system microcontroller via the SMBus interface. Ensure the 3.3V power supply is stable and follows the recommended decoupling layout to maintain USB 2.0 signal integrity.
