Microchip Technology's USB2513B/M2: High-Performance USB 2.0 Multi-TT Hub Controller

The USB2513B/M2 from Microchip Technology is a versatile and efficient solution for expanding USB capabilities in a wide range of applications. This USB 2.0 Hub Controller integrates multiple transaction translators (Multi-TT), which enables optimal performance for connected USB 1.1 devices on a high-speed USB 2.0 bus. The device is designed to support up to three downstream ports, making it an ideal choice for desktop and mobile applications, embedded systems, and consumer electronics that require USB connectivity expansion.

Boasting a high level of integration, the USB2513B/M2 simplifies design efforts and reduces time-to-market. It includes an on-chip 24MHz crystal driver, integrated resistors for upstream and downstream termination, and pull-up/pull-down resistors on the USB data lines, minimizing the need for external components. The controller also features configurable GPIOs that allow for additional customization and functionality within user applications.

One of the key features of the USB2513B/M2 is its support for compound devices, with each downstream port able to support a full-speed or low-speed peripheral behind a high-speed hub. This feature, combined with the Multi-TT architecture, ensures seamless operation and maximizes performance when multiple USB 1.1 devices are connected.

The device is compliant with the USB 2.0 specification and is backward compatible with USB 1.1, ensuring broad compatibility with existing USB devices. It also supports both bus-powered and self-powered modes, providing flexibility in various usage scenarios. Additionally, the USB2513B/M2 incorporates advanced power management features, including individual port power control and overcurrent detection, to further enhance the safety and reliability of the USB hub design.

For ease of programmability, the USB2513B/M2 comes with an integrated serial EEPROM interface, which allows for the customization of device settings and supports the configuration of vendor-specific USB descriptors. This level of customization ensures that developers can tailor the hub to their specific application requirements.

In summary, the USB2513B/M2 from Microchip Technology is a high-performance, feature-rich USB 2.0 hub controller that offers an excellent balance of integration, efficiency, and flexibility for developers looking to expand USB functionality in their products.
