USB2517
Microchip's USB251x is a family of versatile, cost-effective and power-efficient USB 2.0 hub controllers. Leveraging Microchip's innovative MultiTRAK technology that delivers industry-leading data throughput in mixed-speed USB environments, the USB251x family is designed for applications that demand low power and a small footprint without compromising on performance.
Well-suited for consumer and mobile applications, all members of the USB251x family are available in space-saving packages. The common 36-pin package shared among the 2/3/4-port hub controllers measures only 6x6mm and provides an ultra small footprint for space-constrained designs while allowing scalable port expansion from two to four ports. The 7-port USB2517 comes in a space-efficient 9x9mm 64-pin package.
Over 30 programmable features, including Microchip's unique PortMap, PortSwap, TrueSpeed and PHYBoost are designed to aid system designers in simplifying PCB layout and optimizing bill-of-material cost. For applications requiring extended operating temperature range, the USB251x i-temp series is designed to meet -40° to 85°C industrial temperature requirements.
产品特性- High performance, low-power, small footprint hub controller IC with 2, 3, 4, or 7 downstream ports (indicated by the “x” in the part number)
