The CY7C65640A-LTXC is an integrated circuit (IC) component designed by Cypress Semiconductor. It is a low-power, high-performance USB 2.0 hub controller. This IC offers several key features that make it suitable for various USB hub applications.
One of the primary features of the CY7C65640A-LTXC is its USB 2.0 compliance, allowing for high-speed data transfers up to 480Mbps. This makes it ideal for applications requiring fast data communication, such as external hard drives or high-resolution webcams. Additionally, it is backward compatible with USB 1.1 devices.
The IC component incorporates an integrated 4-port hub, eliminating the need for additional external components. This integration saves space on the PCB and simplifies the design process. Each port supports device attach/detach detection, enabling hot-swapping of USB devices without needing to restart the system.
The CY7C65640A-LTXC also features advanced power management capabilities. It supports both self- and bus-powered modes, giving flexibility in choosing power sources. The IC includes an integrated battery-charging detection circuit, which can detect and control the charging of devices like smartphones or tablets.
Another prominent feature is the support for Transaction Translator (TT) mode, which enables the connection of multiple USB hubs in a tiered configuration. This allows for expansion of the number of USB devices connected to a single host controller, creating a more versatile system
