Performance•Low from software TCP/IP bottleneck

and CPU overhead• High from TCP/IP offload

Task to develop• Software porting and integration• Hard to debug

• Just add TCP/IP chip as simple as Memory chip

Knowledge• TCP/IP protocol & OS Kernel• Ethernet drive• Socket programming

• Socket programming

System resource • Faster CPU & bigger Memory• Just add TCP/IP Chip on existing

system

BOM • High from big system resource• Low from small system resource

System upgrade•Need to port TCP/IP whenever

change platform•No need to port TCP/IP even

when change platform

Remote upload•Limited to add new functions on

installed system•Stable to add new functions on

① Monitoring Memory Buffer Status through BRDYn pins. - BRDYn monitors TX/RX memory status of each socket - If Buffer is full, it notifies the status to main MCU - MCU doesn’t need to manage the memory status – can concentrate on other main

jobs② Maximizing the Performance of Data Communication through

DMA - Guarantee Max. more than 70Mbps throughput

③ Flexible Memory Allocation in the Range of 0~64Kbyte - for the Multi-media Stream : bigger memory can be assigned

[CIRCUITCELLAR-New Product News]WIZnet, Inc.-Ethernet Controller for High-End SystemsWIZnet, Inc.-Ethernet Controller for High-End Systems

WIZnet has rolled out its newest chip, the W5300, which is twice as fast and offers more channels than the currently availableW5100. Like its predecessor, the W5300 integrates an Ethernet MAC and PHY as well as a fully hardwired TCP/IP core into aneasy-to-use chip. However, it also enables you to use an external third-party PHY rather than the internal one.

The W5300 offers stable speeds up to 50 Mbps, which is enough to watch movies in real-time rather than on a buffered basis.It also supports eight independent socket channels, provides dynamic memory allocation according to channel throughput, andoffers a 16- or 8-bit data bus. The W5300 has the capabilities to meet Triple Play Service (Broadband Access, VoIP, and digitalbroadcasting) needs.

The estimated cost for the W5300 is $5.99 in 1,000-piece quantities.
