W3150A+ 硬件协议栈芯片
是以大规模集成电路方式硬件化通讯协议栈, 提供一种简单、经济的高速连接互联网上各种数字设备的解决方案。实现方式是以硬件化TCP/IP栈来完成。 提供系统设计科研人员一个既快且简易的渠道来实现以太网的功能。应用此大规模集体化的芯片於系统中可完全卸载网络协议所需的负荷,减轻软件开发的开支。
实现TCP/IP栈中的TCP,UDP,ICMP,IPv4,ARP,IGMP以及PPPoE协议,另加连接以太网协议中的数据控制及MAC协议。芯片内含16KB收/发缓冲存储器。对MCU接口采用直接总线方式,对物理层衔接则应用标准MII接口。因此在IP机顶盒、网络数字录像机、网络电话、VoIP系统单芯片、网络MP3播放机、手提医疗设备、工业监控及仪表, 以及大型家用电器等应用上都是最理想的芯片。
The W3150A+ is an LSI of hardware protocol stack that provides an easy, low-cost solution for high-speedInternet connectivity for digital devices by allowing simple installation of TCP/IP stack in the hardware.
The W3150A+ offers system designers a quick, easy way to add Ethernet networking functionality to any product. Implementing this LSI into a system can completely offload Internet connectivity and processing standard protocols from the system, thereby significantly reducing the software development cost.
The W3150A+ contains TCP/IP Protocol Stacks such as TCP, UDP, ICMP, IPv4, ARP and PPPoE protocols, as well as Ethernet protocols such as Data Link Control and MAC protocol. The total internal memory size is 16Kbytes, which is the buffer for transmit and receive operations.
The W3150A+ provides a local bus interface to various MCUs and standard MII(Media Independent Interface) specification consisting of nibble data bus for Ethernet PHY devices.
The W3150A+ is a best-fitted device for embedded application with Internet-Connectivity including IP- Setop Box, Internet-DVR, Internet phones, VoIP SOC chips, Internet MP3 players, handheld medical devices, various industrial system monitoring and metering, and many other non-portable electronic devices such as large consumer electronic products.
