I have a couple of questions. Is there somewhere to download the STVD9 development software? Also, is the ST9 still in production, and if so, what distributors have any stock?
For anyone who might stumble onto this thread in the future, I was able to find the ST9 GNU tools at the internet archive. http://www.archive.org/
Only one part is currently active, click down into the part and check distributor availaibility
ST9 8-bit MCUs - STMicroelectronics
Perhaps a conversation you'd want to have with the local ST Sales office?
I've checked all the usual distributors, and nobody has stock. I'm so tired of ST's extremely poor customer service, and always listing old parts as "ACTIVE" when they clearly are NOT. We've had nothing but continuous supply issues with ST components over the years. If you are not a preferred customer in the Automotive sector, they really do not care to give you the time of day.
Anyway, does anyone have a source to download the STVD9 software? I'm not at all familiar with the ST9 architecture, but I have an old project I'm looking at that was based on ST9. Are the newer ST MCU's at all backward compatible with the ST9? Would it take much to convert an ST9 binary to run on the newer MCU's? Is there a compiler or assembler/disassembler still available for it?
There used to be GNU tools so I suspect some of that is still available in some form. Find people on LinkedIn claiming ST9 experience, or those who staffed your older ST9 projects.
The semi conductor industry has changed in the last decade or two, if a part is not running at high enough volumes the fab space and design teams are going to focus on things that are. I've lost a bunch of parts to EOL based on the shuttering of plants, loss to tsunamis, break down of obsolete equipment, mergers, and migration of wafer production to consumer LED/lighting. There isn't speculative production, most everything has to have an order behind it, and 26-52 week lead times are not unusual.
The people doing $B of sustaining business are going to be driving the bus, so Ford, GM, VW, BMW, Apple, Nike, Whirlpool, etc. Look at what the high running parts are at the distributor and manufacturer levels.
