MCHPUSB2514BI-AEZG
Overview
The USB2514BI-AEZG is an industrial-grade, low-power 4-port USB 2.0 hub controller designed for high-performance embedded applications. It features MultiTRAK technology, providing a dedicated Transaction Translator for each downstream port to ensure maximum data throughput even when mixing high-speed and full-speed devices. The controller is fully compliant with USB 2.0 specifications and supports advanced power management and battery charging.
Why Choose This Part
This controller offers excellent signal integrity via PHYBoost, which allows for programmable USB signal drive strength to compensate for PCB trace losses. It simplifies design with internal USB termination resistors and supports PortSwap for flexible PCB routing of differential pairs. The industrial temperature rating of -40 degC to 85 degC ensures reliable operation in demanding environments.
Applications
Key Specifications
Getting Started
Designers can configure the device using an external EEPROM or via SMBus for custom Vendor and Product IDs. Use a 24 MHz crystal or external clock source to drive the internal PHY. Microchip provides the EVB-USB2514 evaluation board as a reference design to accelerate hardware development and validation.
