USB2513B-AEZC屬于集成電路（IC）的控制器。由微芯科技股份有限公司制造生產的USB2513B-AEZC控制器該系列產品主要用于在采用不同通信協(xié)議和/或信令方法的端點之間提供信息連接。示例包括將 I2C 總線連接到 UART，將 USB 連接到 I2C、SPI、以太網(wǎng)或 UART、以太網(wǎng) MAC 和 PHY 等的器件。此外，還包括用于通過為點對點通信設計的接口建立多路連接的器件，例如 USB 集線器控制器。

General Description

The Microchip USB251xB/xBi hub is a family of low-power, configurable, MTT (multi transaction translator) hub controller IC products for embedded USB solutions. The x in the part number indicates the number of downstream ports available, while the B indicates battery charging support. The Microchip hub supports low-speed, full-speed, and hi-speed (if operating as a hi-speed hub) downstream devices on all of the enabled downstream ports.
