ADM6996L集成电路（IC）的控制器规格书PDF中文资料

ADM6996L属于集成电路（IC）的控制器。由英飞凌科技股份公司制造生产的ADM6996L控制器该系列产品主要用于在采用不同通信协议和/或信令方法的端点之间提供信息连接。示例包括将 I2C 总线连接到 UART，将 USB 连接到 I2C、SPI、以太网或 UART、以太网 MAC 和 PHY 等的器件。此外，还包括用于通过为点对点通信设计的接口建立多路连接的器件，例如 USB 集线器控制器。

Overview

The ADM6996L is a high performance, low cost, highly integration (Controller, PHY and Memory) five-port 10/100 Mbps TX/FX plus one 10/100 MAC port Ethernet switch controller with all ports supporting 10/100 Mbps Full/Half duplex. The ADM6996L is intended for applications to stand alone bridge for low cost SOHO market such as 5Port, Router application.
