Infineon ISP752RFUMA1: High-Performance USB 2.0 Hub Controller for Embedded Systems
The demand for robust and high-speed peripheral connectivity in embedded systems continues to grow, driven by applications in industrial automation, medical devices, point-of-sale terminals, and advanced computing. Addressing this need, the Infineon ISP752RFUMA1 stands out as a premier high-performance USB 2.0 hub controller engineered specifically for the rigorous demands of embedded environments. This device integrates advanced features to deliver reliable, scalable, and efficient USB connectivity.
At its core, the ISP752RFUMA1 is a 4-port hub controller that supports the USB 2.0 specification, enabling data transfer rates of up to 480 Mbps on the high-speed upstream port. This ensures seamless connectivity for a multitude of peripherals—from keyboards and mice to high-bandwidth data acquisition modules—without creating a bottleneck in the system's data flow. Its architecture is designed for low power consumption, a critical factor for power-sensitive embedded applications, and includes advanced power management features such as individual port power switching and over-current detection.
A key strength of this controller is its enhanced electrostatic discharge (ESD) protection, which significantly surpasses standard industry requirements. This robust built-in protection ensures greater reliability and longevity in harsh operating conditions, reducing the need for additional external components and simplifying board design. Furthermore, the hub supports multi-transaction translator (Multi-TT) functionality. This allows each downstream port to handle multiple full-speed or low-speed transactions simultaneously, drastically improving overall bandwidth utilization and reducing latency when multiple slower devices are connected.
The ISP752RFUMA1 is offered in a compact 64-pin QFN (Quad Flat No-leads) package, making it an excellent choice for space-constrained PCB designs. Its compatibility with a wide operating voltage range and extended industrial temperature ranges further underscores its suitability for challenging embedded and industrial applications. For developers, Infineon provides comprehensive support, including proven reference designs and evaluation boards, to accelerate integration and time-to-market.
ICGOODFIND: The Infineon ISP752RFUMA1 is a superior USB 2.0 hub controller that delivers a powerful combination of high-speed performance, robust integrated protection, and exceptional power efficiency. It is an ideal solution for developers building next-generation embedded systems that require dependable and scalable USB connectivity.
