WIZnet W3150A+: Enhanced Ethernet-stack IC features an SPI interface
Dec 1 2006 12:13PM | Permalink |Comments (0) |
Adding an SPI-interface and faster access to transmit/receive memory to the W3150Z Ethernet stack IC, the fully-hardwired W3150A+ TCP/IP stack also features a dynamic adjustable internal 16 Kbyte Tx/Rx buffer-size allocation. The device supports ADSL connection with PPPoE (Point-to-Point Protocol Over Ethernet), port-unreachable information in UDP (User Datagram Protocol), four independent, concurrent sockets, and full-duplex mode. Throughput includes 8051 with a 1-Mbps maximum, AVR with an 8-Mbps maximum, ARM7 with a 21-Mbps maximum, and a 10/100 Base-T Ethernet with auto-detection. The device provides DHCP (Dynamic Host Configuration Protocol), TELNET, FTP, HTTP, and DNS (Domain Name Server) X source code with the evaluation board. Available in a 64LQFP ROHS (restriction-of-hazardous-substances) package, with a 3.3V supply voltage, 5V I/O tolerant; the device costs $5 (10,000).
