Project Description

This article represents  the comparison of new W5500.

He shows 3 point to explain this :

1. Price

The result of these cost reduction processes can be seen in the pricing information fromDigikey. The price per 1,000 for W5100 is $4.32 each, whereas the W5500 is $2.64 each.

2. Implementation

The W5500 is available in 48LQFP which is aimed squarely at low tech solutions. The W5200 was only available in 48QFN which made it more difficult to use the chip in low volume applications.

3. Performance

The ping results were slightly slower than previously seen on the w5200. But I believe that is an external issue, possibly resulting from a change in my network. I have repeated the test with the W5200, and now get similar performance too.

And, AVRFreeRTOS(also AVR firmware) version code is available at the original blog. It’ good idea that let’s join this project if you’re interested in AVR programming & Internet.
