I agree with your remark Max. This information is missing.
However, I found this application note from ST that tells you how to use the ST92F150-EMU2 emulator for emulating the ST92F I have attached this document to this message. Check paragraph 2 because not all the ST92F250 features are supported by this emulator, there are some limitations. However, It looks like that's the only emulator supporting this device so you will have to live with it. Programmer-wise, the ST92F150-EPB supports both ST92F150 and ST92F The latest programmer software from ST (STVP9 will do the job) since right now STVP9 1.9.5 has a ST92F250 option in one of its menu. Last but not the least the ST9GP-EVAL evaluation board supports ST92F120, F124, F150 and F Everything you need to be an happy ST9 developper. That's a pretty nice evaluation board. It will help you getting started with ST9. Take care, Jojo
