The USB2514B-AEZC is a compact, high-performance USB 2.0 hub controller from Microchip, designed to extend USB connectivity in space-constrained applications. It leverages MultiTRAK® technology to deliver industry-leading data throughput in mixed-speed USB environments while maintaining ultra-low power consumption. Ideal for consumer and mobile electronics, it provides a 4-port USB 2.0 hub solution in an ultra-compact package.

Key Features

• USB 2.0 compliance: Supports Hi-Speed (480 Mbps), Full-Speed (12 Mbps), and Low-Speed (1.5 Mbps) devices.
• Space-saving design: 4-port hub in a 36-pin QFN package (6×6 mm), minimizing PCB footprint.
• MultiTRAK® technology: Optimizes data throughput in mixed-speed environments without performance loss.
• Programmable flexibility: Over 30 customizable features, including PortMap, PortSwap, and PHYBoost, to simplify PCB layout and reduce costs.
• Battery charging support: All downstream ports operate as Charging Downstream Ports (CDP), enabling USB Battery Charging 1.1 (BC1.1) for fast device charging.
• Low-power operation: Ultra-low standby current (<1 µA) extends battery life in portable devices.

Common uses include consumer electronics (tablets, peripherals), mobile devices (smartphones, dongles), IoT hubs, industrial interfaces, and embedded systems requiring USB expansion. Its compact size and charging capabilities make it suitable for battery-operated or space-limited designs.

The USB2514B-AEZC combines high-speed USB performance, ultra-compact form factor, and advanced programmability to address connectivity needs in portable and embedded systems. Its MultiTRAK® efficiency and charging support make it a versatile solution for expanding USB functionality while minimizing power and space constraints.
