Test plan in -40 to +85 degrees at 80 MHz speed(W5500)

hello everyone
This is Bruno.

I am preparing a new project.
Tests related to the W5500 specs

1.80Mhz

2.  Operating temperaure -40~+85

I fell in love with two specifications first, so I'm going to do related tests with my colleague Teddy.
(Teddy previously conducted 80Mhz tests with the W6100. Link: https://maker.wiznet.io/teddy/projects/stm32h723-w6100-spi-dma-fast-data-transmission/)

I'm worried that there may be some parts that don't fit the specifications, but I'm going to go ahead and try to find a possible way or try to secure it.

Coming Soon~
