TCP/IP On A Chip

The W3150A+ is a new, fully hardwired TCP/IP stack that gives even low-end microcontrollers Internet capabilities at full speed.

It has dynamically adjustable Tx/Rx buffer-size allocation, aimed at optimizing multimedia Internet transmission. It incorporates a TCP/IP stack and a future-proofed 10/100 Ethernet MAC. The peripheral chip supports IGMP for multimedia streaming, supports ADSL connection (with PPPoE), has simplified internal register access and command operations for TCP, UDP, IPv4, ARP, ICMP, IGMP, PPPoE, and Ethernet MAC; supports a keep-alive function; and gives max throughput rates of 1 Mbps when used with an 8051, 8 Mbps with an AVR, 21 Mbps with an ARM7. C source code is provided with evaluation board.
