The USB4604-1080HN port controller is a part of the USB4604 family of integrated port controllers for Universal Serial Bus (USB) host applications. It supports the SuperSpeed (USB 3.1 Gen 1) and Hi-Speed (USB 2.0) ports. This integrated port controller has two data lanes (D+ and D-) and provides Type-C port detection, which operates in a host system that is compliant with USB specifications up to USB 3.1 Gen 1. Additionally, the USB4604-1080HN port controller supports the USB attach and detach feature, so that the host can detect when a device is connected to one of its ports.

The USB4604-1080HN port controller is designed to provide a low-cost solution for USB port expansion, which is ideal for applications like embedded systems, consumer electronics and automotive infotainment. It supports the USB attach and detach events from the connected device, allowing the host to detect when the device is connected or disconnected. The USB4604-1080HN port controller also features an integrated Type-C plug detection circuit, which can detect when an available Type-C plug is connected to the port.

The USB4604-1080HN port controller is programmed using a standard I2C bus and supports the Hot Plug Detect (HPD) protocol, which allows the host to detect when the port is in use. The USB4604-1080HN port controller also supports the SuperSpeed Protocol and Hi-Speed Protocol, which are mandatory protocols for the USB 3.1 Gen 1 and USB 2.0, respectively. In addition, the USB4604-1080HN port controller supports two additional ports for further customizations, allowing you to add extra features to the controller.

The USB4604-1080HN port controller works in the following four stages of operation:

• Idle Stage: When no device is connected to the port, the controller stays in the idle state.
• Attach Stage: When the device is connected to the port, the controller will detect the presence of the device and switch to the Attach stage, where it will process and analyze the device\'s request.
• Data Transfer Stage: Once the device request is accepted, the controller will then start to transfer data between the host system and the device.
• Detach Stage: When the device is disconnected from the port, the controller will enter the Detach stage, where it will clean up the connection.

The USB4604-1080HN port controller is a versatile, cost-effective solution for USB port expansion and is ideal for applications like embedded systems, consumer electronics and automotive infotainment. It provides both SuperSpeed and Hi-Speed ports and features an integrated Type-C plug detection circuit. Additionally, the controller supports the USB attach and detach events from the connected device, enabling the host to detect when a device is connected or disconnected.
