描述 Description

●Fully hardwired network protocol & MAC
●Direct & Indirect BUS & ?SPI for Host Interface
●Various External PHY usable such as Switching PHY
●Stable Data Communication
The W3150A+ chip is a Hardwired TCP/IP embedded Ethernet controller that enables easier Internet connection for embedded systems.
W3150A+ suits users in need of stable Internet connectivity best, using a single chip to implement TCP/IP Stack & 10/100 Ethernet MAC . Hardwired TCP/IP stack supports TCP, UDP, IPv4, ICMP, ARP, IGMP, and PPPoE, …, which has been proven through various applications over many years.?W3150A+ uses a 16Kbytes internal buffer as its data communication memory.
By using W3150A+, users can implement the Ethernet application they need by using a simple socket program instead of handling a complex Ethernet Controller.
It is possible to use 4?independent hardware sockets simultaneously. BUS & SPI (Serial Peripheral Interface) is provided for easy integration with the external MCU.
As it doesn’t have the PHY, users can interface any external PHY such as switching PHY according to their requirement.

特性 Features

●Hardwired TCP/IP protocols :?TCP, UDP, ICMP, IPv4, ARP, IGMP, PPPoE
●Un-attackable hardware network engine for preventing network attacks such as flooding, spoofing, injection
●Host Interface : Direct/Indirect BUS & Serial Peripheral Interface (SPI MODE 0,3)
●4 Independent hardware socket
●Internal 16Kbytes memory for TCP/IP packet processing
●MII Interface for Ethernet PHY chip
●3.3V Operation with 5V I/O signal tolerance
●64LQFP lead-free package (10x10mm)

簡介

W3150A+屬于集成電路（IC）的控制器。由制造生產(chǎn)的W3150A+控制器該系列產(chǎn)品主要用于在采用不同通信協(xié)議和/或信令方法的端點(diǎn)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(diǎn)對(duì)點(diǎn)通信設(shè)計(jì)的接口建立多路連接的器件，例如 USB 集線器控制器。
