USB2512B-I/M2 General Description
Microchip's USB251xB 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 USB251xB family is a USB port expansion solution for applications that demand ultra low power and a small footprint without compromising on performance.
Well-suited for consumer and mobile applications, all members of the USB251xB family are available in a space-saving package. The common 36-pin package shared among the 2/3/4 port hub controllers measures only 6x6 mm and provides an ultra small footprint for space-constrained designs while allowing scalable port expansion from two to four ports.
Over 30 programmable features including Microchip's unique PortMap, PortSwap, and PHYBoost are designed to aid system designers in simplifying PCB layout and optimizing bill-of-material cost. Every downstream port of the USB251xB hubs can be enabled to support USB Battery Charging 1.1 specification as a Charging Downstream Port (CDP). A CDP provides universal battery charging capability to a compliant mobile phone or portable electronic device using a standard USB port.
The USB251xB supports an extended operating temperature range of 0° to 85°C. The USB251xBi is designed to meet -40° to 85°C industrial temperature requirements. Note that the "M2" product versions are targeted for new designs. The M2 products are manufactured on the latest production flow offering improved efficiencies and capacity. No product versions of the USB251xB are near the end of life, with all versions maintaining full production release status.
