Microchip Technology USB2514B/M2 - USB 2.0 Hi-Speed Hub Controller
The USB2514B/M2 from Microchip Technology is a versatile and high-performance USB 2.0 Hi-Speed hub controller, which is part of their comprehensive line of USB solutions. This advanced IC is designed to enable a single USB host to interface with multiple downstream USB devices, offering a convenient and efficient way to expand USB connectivity in a variety of applications.
Key Features:
- Multi-TT Architecture: With the Multi-Transaction Translator (Multi-TT) architecture, each downstream port benefits from its own dedicated transaction translator. This feature ensures the highest bandwidth and is particularly beneficial when mixing USB 2.0 and lower-speed USB devices.
- PortMap and PortSwap: The USB2514B/M2 includes Microchip’s unique PortMap and PortSwap features, which allow for flexible port configuration and simplify PCB layout by enabling the logical order of the downstream ports to be remapped.
- Automatic Link Power Management (ALPM): This energy-efficient feature helps to reduce power consumption by allowing the device to enter a low-power state when the USB link is not active, making it ideal for battery-powered applications.
- Comprehensive Support: The device is supported by Microchip's robust software and hardware tools, which help to streamline the development process and reduce time to market.
Applications:
The USB2514B/M2 is suitable for a wide range of applications, including but not limited to:
- Desktop and Notebook PCs
- Docking Stations
- Monitor Hubs
- Printers and Multi-function Printers
- Standalone USB Hubs
Technical Specifications:
- USB 2.0 Hi-Speed (480 Mbps) and Full-Speed/Low-Speed (12 Mbps/1.5 Mbps) compliant
- Industry-standard 36-pin QFN package
- Integrated, 5V to 3.3V, and 1.8V regulators
- Support for battery charging specifications (for example, Apple, SE1)
The USB2514B/M2 hub controller is an excellent choice for designers looking to implement USB 2.0 connectivity with high bandwidth and advanced power management features. It combines functionality and flexibility to meet the demands of a wide array of USB-enabled devices.
