May I know, what are the replacement parts for the STMicro Micro Controllers STR911FAM44X6 & STR911FAM42X6?
Is this an 8-bit MCU ?
I suggest to approach ST directly, e.g via an FAE, or an official distributor.
This is ST's Cortex M forum, not much about legacy stuff.
Or try the STM8 forum, which is supposedly similar.
The STR9 is an ARM9 (ARM966E-S)
Define "replacement", you're going to have to redesign your board using current parts, we moved to the STM32 family a decade ago.
Support incident created, contacting customer, will work with them until resolved.
