SUBJECT W5200 LEDs blinking at startup
NAME WIZnet DATE 2013-09-30 HIT 2806

Dear customer.

Thanks for your interest in W5200.


W5200 has regulator so although w5200 receives 3.6V, it could work fine.

Please send me your schematic and ROT number, then we will check more and tell you answer.


Thanks.

WIZnet.


When I plug my W5200 board, both LEDs (nSPD and nLINK) blink 4 times and then the W5200 starts working at 10Mbps.

This is happening on some chips and at 3.6V.

When I power them from 3.3V, everything is fine, W5200 starts working right away at 100Mbps.

What do those 4 blinks mean?
