Microchip USB2534I-1080AENTR: A Robust 4-Port Hub Controller for Demanding Embedded Applications
In the rapidly evolving landscape of embedded systems, reliable and high-performance connectivity remains a cornerstone. The Microchip USB2534I-1080AENTR stands out as a premier solution, engineered specifically to address the complex USB hub requirements of modern embedded designs. This highly integrated 4-port hub controller provides a seamless and robust interface for expanding USB capabilities in a wide array of applications, from industrial automation and medical devices to point-of-sale systems and smart appliances.
At its core, the USB2534I is a low-power, OEM-configurable hub controller based on Microchip's proven and field-upgradable USB 2.0 hub architecture. It supports data transfer rates up to 480 Mbps on the upstream port and distributes this bandwidth across its four downstream ports, ensuring efficient data flow for multiple peripherals simultaneously. A key feature of this controller is its support for both battery charging (BC) revision 1.2 and dedicated charging port (DCP) modes. This allows devices like smartphones and tablets to charge at their maximum potential rate, even when the host system is powered off or in a low-power state, a critical function for always-available end products.
The device is designed for exceptional ease of integration and flexibility. It requires a minimal number of external components, which simplifies PCB layout, reduces the overall bill of materials (BOM) cost, and saves valuable board space. Furthermore, its non-volatile memory (NVM) allows for extensive customization of vendor IDs, product IDs, and port configurations without requiring external serial EEPROMs in most cases. This programmability enables manufacturers to tailor the hub's functionality and identity to their specific system requirements, streamlining the branding and development process.
For developers operating in challenging environments, the USB2534I-1080AENTR offers enhanced reliability. Its industrial temperature range qualification ensures stable operation in conditions where commercial-grade components would fail. Advanced system-level features like port mapping, disablement, and PHY boosting provide designers with precise control over signal integrity and port behavior, guaranteeing consistent performance across diverse use cases.
ICGOOODFIND: The Microchip USB2534I-1080AENTR is an optimal choice for designers seeking a highly integrated, reliable, and feature-rich USB 2.0 hub solution. Its combination of low-power operation, advanced charging support, and OEM configurability makes it an indispensable component for building next-generation embedded systems that demand robust and versatile connectivity.
