TUSB2136PM is a USB 2.0 Hub Controller developed by Texas Instruments (TI). It enables a USB host controller to connect to multiple downstream USB hub ports by a single USB connection. The TUSB2136PM is targeted for universal serial bus (USB) 2.0 applications that require upstream bandwidth of up to 480 Mbps and support up to 15 downstream ports.

Features

TUSB2136PM provides the following features:

• Integrated OTG controller and PHY meeting USB 2.0 specification
• Support for embedded Web Based Management
• Support for high speed (480 Mbps), full speed (12 Mbps) and low speed (1.5 Mbps)
• Supports three transaction translators and static map configuration to enable more than one hub port per port
• Provides up to 15 downstream USB ports (max 64 through chain looping)
• Integrated thermal shutdown circuitry
• Integrated PHY Link Partner Reservation (LPR) circuit
• Automatic Self Recovery from malfunctioning Hubs
• Programmable Port Ordering for Hub Management

Application Field

TUSB2136PM is most commonly used in USB hubs and other point-to-point USB 2.0 devices, such as keyboards, mice and peripherals. It is also ideal for USB 2.0 automotive systems, networked storage, and consumer electronics.

Working Principles

TUSB2136PM\'s working principle utilizes a USB 2.0 tranasctor to translate high-speed downstream signals. The hub then splits the high-speed data stream into full-speed and low-speed data streams. The primary benefit of this approach is that it allows devices to communicate with a hub while using different speeds. When a device is connected, it negotiates its bandwidth by communicating with the hub to find the best available speed. If the device is communicating with a USB hub, the hub must use the same speed as the device and convert the signal to the appropriate speed.The TUSB2136PM supports the USB On-The-Go (OTG) protocol. This means that the device can act as both a host and a peripheral and communicate with other USB devices. The TUSB2136PM also supports the power management features of the USB 2.0 specification. This allows it to provide additional power to individual ports, which is especially helpful for low-power devices. The USB 2.0 supports the Link Power Management (LPM) protocol, which enables hubs to put ports into a low-power state when data is not being transferred. This helps to reduce power consumption and reduce the heat generated by the hub, which can lead to an improved user experience.In conclusion, TUSB2136PM is a reliable and efficient USB hub controller that can be used in a variety of applications. It is an easy to use and cost-effective solution for USB 2.0-based applications. The TUSB2136PM can handle high-speed data streams and enable devices to communicate with each other without sacrificing performance or sacrificing power consumption.
