Any updates on the topic?
There is an IDE available for download on their webpage:
http://bjxmcu.com/index/mcu.htmlAnd there is also a "Writer" which writes programs to either OTP or "MTP" (as they call it on their website) controllers:
http://bjxmcu.com/index/productkf.htmlUnfortunately neither TaoBao nor 1688.com have anything listed for "BJXDWTR" - so I am not sure if it is possible to program these chips at all!
They have a few controllers listed here:
http://bjxmcu.com/index/product/ptid/2.html but most of them aren't available through TaoBao or 1688.com - which tells me this is a pretty niche company if even TaoBao doesn't list the majority.
If I start "compiler.exe" (found in the IDE download package) I just get this error message in chinese (see attached images) - anyone able to translate this? "CompilerDLL.dll" is right next to "compiler.exe" in the same folder so that shouldn't be the problem.
If I open "BjxMTPWriter.exe" there are only 3 chips available from the dropdown menu: "BJ8M601A, BJ8M602A, BJ8M603A". So this tool is missing a couple of chips. I am wondering if there also is a "BjxOTPWriter.exe" - at least not in the IDE.rar package

Seems like this is a dead end for now
Edit: Their last chip on the "New IC"-section:
http://bjxmcu.com/index/product/ptid/1.html is from 2014.
Edit_2: @westfw There is a chinese company selling multi device programmers, there are some which are able to program the "TMP47P422VF", although it is not the exact same chip if they are compatible enough it could work, full supported devices are listed here:
