The USB2513BI-AEZG: A Compact Powerhouse for USB 2.0 Hub Expansion
In the realm of connectivity, the need for expanding a single USB host port into multiple ports remains ubiquitous. The USB2513BI-AYZG from Microchip Technology stands out as a highly integrated, industrial-grade solution designed to meet this demand with exceptional reliability and efficiency. This 3-port USB 2.0 hi-speed hub controller is engineered to provide a seamless and transparent expansion experience for a wide array of applications, from embedded systems and industrial machinery to consumer peripherals.
A key strength of the USB2513BI-AEZG lies in its complete system integration. The controller incorporates all essential components, including the USB 2.0 transceivers, a hub controller, and termination resistors. This high level of integration significantly simplifies design-in, reduces the external bill of materials (BOM), and minimizes the required PCB footprint, making it an ideal choice for space-constrained designs. Developers can achieve a fully functional 3-port hub with minimal external components, accelerating time-to-market.
The device is fully compliant with the USB 2.0 specification and supports low-speed (1.5 Mbps), full-speed (12 Mbps), and hi-speed (480 Mbps) data rates. Each of its three downstream ports can independently operate at any of these speeds, ensuring optimal performance for any connected device, be it a hi-speed video capture card or a low-speed keyboard. This flexibility is crucial for modern systems that must interface with a diverse ecosystem of peripherals.
Furthermore, the USB2513BI-AEZG offers advanced features that enhance its robustness and usability. It supports individual or ganged power switching and over-current protection for each downstream port. This allows designers to implement precise power management, safely powering or shutting down specific ports without affecting others—a critical feature for industrial applications where fault isolation is paramount. The controller also features non-removable ports, which are permanently enabled, streamlining the design by eliminating the need for external port status indicators.
Packaged in a compact 36-pin SQFN lead-free package, the device is built for durability and efficient manufacturing. Its industrial temperature range qualification ensures stable operation in harsh environments, underscoring its suitability for demanding applications beyond typical consumer use.
ICGOOFind: The Microchip USB2513BI-AEZG is a superior, fully-integrated 3-port USB 2.0 hub controller that delivers robust performance, design simplicity, and power management flexibility. Its high level of integration and industrial-grade features make it an outstanding choice for developers seeking a reliable and efficient connectivity solution.
