MICROCHIP USB 2.0 Hub Controller IC, 36-Pin QFN, 3.3V

The MICROCHIP USB2514BI-AEZG is a versatile and power-efficient USB 2.0 hub controller integrated circuit designed for modern electronic designs demanding port expansion in a compact form factor. Leveraging Microchip's innovative MultiTRAK™ technology, it delivers industry-leading data throughput in mixed-speed USB environments, making it an ideal solution for applications that require ultra-low power consumption and a minimal footprint without compromising on performance.

Well-suited for consumer electronics, mobile devices, and industrial applications, this controller is part of the USB251xB/xBi family and is housed in a space-saving 36-pin QFN package measuring only 6x6 mm. This ultra-small footprint is perfect for space-constrained designs while allowing scalable port expansion from two to four downstream ports. The device is fully compliant with the USB 2.0 specification, supporting data rates up to 480Mbps.

Key Features & Technology

• MultiTRAK: A high-performance multiple transaction translator that provides one transaction translator per port, optimising data flow.
• PortMap: Offers flexible port mapping and disable sequencing for custom configuration.
• PortSwap: Programmable USB differential-pair pin locations ease PCB design by aligning signal lines, simplifying layout.
• PHYBoost: Programmable USB signal drive strength helps recover and maintain signal integrity over varying trace lengths.
• Power Management: Features full power management with individual or ganged power control of each downstream port and supports a single external 3.3V supply source. Internal regulators provide a 1.2V core voltage.
• Integrated Design: Comes with fully integrated USB termination and pull-up/pull-down resistors, an on-board 24MHz crystal driver (also supports ceramic resonators or external 24/48MHz clock input), and 4kV HBM ESD protection.
