Wasn’t there a law about exporting 32bit processors!!! Maybe this made sense 30 years ago but now any toy has a 32bit!.. anything less is forbidden at GHI
Seems normal for mouser.com
I ordered last year a few LPC936 (8-Bit 8051 family) and got the same paper.
The second time I ordered a development kit for a analog processor from AD (also8-Bit 8051 family), again I got this paper.
My answers where always “bulding a washing mashine”
