USB2512B-AEZG

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.

Microchip的USB251xB是一系列多功能、高性价比、高能效的USB 2.0集线器控制器。USB251xB系列利用Microchip创新的MultiTRAK技术在混合速度USB环境中提供业界领先的数据吞吐量，是一款USB端口扩展解决方案，适用于要求超低功耗和小尺寸而不影响性能的应用。

USB251xB系列的所有产品均采用节省空间的封装，非常适合消费电子和移动应用。2/3/4端口集线器控制器之间共享的通用36引脚封装尺寸仅为6x6 mm，为空间受限的设计提供了超小的尺寸，同时允许从两个端口扩展到四个端口。

包括Microchip独特的PortMap、PortSwap和PHYBoost在内的30多种可编程特性旨在帮助系统设计人员简化PCB布局和优化物料成本。USB251xB集线器的每个下游端口都可以支持USB电池充电1.1规范，作为充电下游端口(CDP)。CDP使用标准USB端口为兼容的移动电话或便携式电子设备提供通用电池充电功能。

USB251xB支持0至85°C的扩展工作温度范围，USB251xBi旨在满足-40至85°C的工业温度要求。请注意，“M2”产品版本是针对新的设计。M2产品采用最新的生产流程制造，提高了效率和产能。USB251xB的任何产品版本都没有接近生命周期，所有版本都保持完整的生产发布状态。
