LAN9500I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LAN9500I控制器該系列產品主要用于在采用不同通信協議和/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、以太網或 UART、以太網 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。

OVERVIEW

The LAN950x is a high performance solution for USB to 10/100 Ethernet port bridging. With applications ranging from embedded systems, set-top boxes, and PVRs, to USB port replicators, USB to Ethernet dongles, and test instrumentation, the device is targeted as a high performance, low cost USB/Ethernet connectivity solution.

The LAN950x contains an integrated 10/100 Ethernet PHY, USB PHY, Hi-Speed USB 2.0 device controller, 10/100 Ethernet MAC, TAP controller, EEPROM controller, and a FIFO controller with a total of 30 KB of internal packet buffering. Two KB of buffer memory are allocated to the Transaction Layer Interface (TLI), while 28 KB are allocated to the FIFO Controller (FCT).

The internal USB 2.0 device controller and USB PHY are compliant with the USB 2.0 Hi-Speed standard. The device implements Control, Interrupt, Bulk-in, and Bulk-out USB Endpoints.
