Can i use mdk-lite version(32k limited) in my company?(not person) I cannot find any rules in licence dacument.
Thank you.
If you want a definitive answer on this, you should contact Keil (or your Distributor/Agent) direct - contact details at the foot of the page.
But there is no longer any restriction on using the Lite version in commercial projects:

Actually you may only use it for evaluation purposes. No commercial end-product shall be produced.

Note that you are replying to a post from over 4 years ago!
At that time, the licence did allow commercial use.
That has, indeed, now changed.
EDIT
See:
https://community.arm.com/developer/tools-software/tools/f/keil-forum/43824/mdk-lite-licensing-issue/159517#159517
As stated there, there is no specific mention at all in the demo version restrictions about whether commercial use is allowed or not.
