The W3150A+ has dynamically adjustable Tx/Rx buffer-size allocation, aimed at optimising multimedia Internet transmission.
The W3150A+ combines a TCP/IP stack with a future-proofed 10/100 Ethernet MAC.
Engineers are wise to offload the burden of the TCP/IP stack into a second peripheral chip (complete with Ethernet MAC) because it can reduce debug issues and time to market with the design of the TCP/IP stack avoided, and the additional benefit of a more stable product.
Simple 8bit micros immediately have much more power as they no longer have the burden of TCP/IP protocols.
TCP-offload improves overall system performance, reduces cost, power and size, and increases robustness.
Engineers no longer need to have detailed knowledge of TCP/IP as this is all accomplished within the IC.
Importantly, W3150A+ supports IGMP for multimedia streaming.
The W3150A+'s hardware TCP/IP stack allows communications to run at close to line speeds, encapsulating and stripping data streams rapidly.
This is also advantageous for avoiding DOS (denial of service) attacks, making it almost impossible to run malicious code causing buffer overruns and the like.
Application examples include: HDTV streaming, digital camera/phone image transmission, portable game players, multimedia streaming etc Designed by WIZnet (Korea) and introduced at the Embedded Systems Conference, the W3150A+ is available from stock from WIZnet's distributor Saelig, with pricing less than US $5 in 10,000-unit quantities.
