I’m planning to integrate W7100A chip for TCP/IP to RS232 conversion and right now I’m using WIZ107RS module and it works absolutely fine. I will follow the schematic diagram Rev1.4 in the design and will buy the chip from RS UK (758-1036)
For my new design, Could you please advise me on the following:
Can I use alternative components instead of the once on the schematic?
According to your forums the chip comes with boot loader pre-installed, is that means it’s ready to run i.e. Also have 4.03 firmware installed?? I’m a bit confused here!
If NOT could you please advise on how to program it? Programmer needed? Link to where to buy it from in UK? And most importantly how to connect it to the chip (electronic schematic if possible)? Can I use PICKIT3 or JTAG Programmer? Etc.?
I’d like it running 4.03 firmware the same as the module!
Is there anything else that I need to pay attention to in my design?
I already know about W7100-S2E chip which it comes ready to use, but it’s not widely available and prefer to use W7100A.
Thanks a lot for your help and I look forward to hearing from you in the near future.
