Infineon ISP752R: High-Performance USB 2.0 Hub Controller for Embedded Systems

The increasing complexity of modern embedded systems demands robust and high-performance connectivity solutions. At the heart of many such designs is the USB hub, a critical component for expanding a single host controller port into multiple ports, enabling communication with numerous peripherals simultaneously. The Infineon ISP752R stands out as a premier dedicated USB 2.0 hub controller engineered specifically to meet the rigorous demands of embedded applications, ranging industrial automation and medical equipment to point-of-sale terminals and gaming systems.

A key strength of the ISP752R lies in its exceptional system integration and power efficiency. The controller integrates a USB transceiver, Serial Interface Engine (SIE), and advanced hub logic into a single chip. This high level of integration significantly reduces the bill of materials (BOM) and simplifies PCB layout, which is crucial for space-constrained embedded designs. Furthermore, it features comprehensive power management capabilities, including individual port power switching and over-current detection for each downstream port. This allows designers to implement sophisticated power control strategies, ensuring compliance with the USB power delivery specification and protecting connected devices from fault conditions.

Performance and reliability are paramount in embedded environments where system failures are not an option. The ISP752R supports full-speed (12 Mbps) and high-speed (480 Mbps) data rates, ensuring compatibility with a vast ecosystem of USB 2.0 devices. Its robust design ensures stable data transfer, which is critical for applications involving data acquisition or real-time control. The hub supports multiple downstream ports (typically 4) and employs a programmable downstream port mapping, offering designers flexibility in configuring the hub's behavior to suit specific system requirements.

For developers, the ISP752R simplifies the design-in process. It is available in compact, industry-standard packages, making it suitable for high-volume manufacturing. Its compatibility with various operating systems minimizes software driver development overhead, allowing for faster time-to-market. Infineon's strong legacy in providing reliable semiconductor solutions for the automotive and industrial sectors further underscores the durability and longevity of this component, making it a trusted choice for products with long lifecycles.
