For people who are outside the coffee machine design engineering field, what are the actual requirements?

What functionality does the existing MCU implement? Do you have any of the design documents or source with which to gauge the complexity, functionality, and number of interfaces it drives or senses?

Perhaps something in the STM8 family?

Not something massively complex, with low cost, and availability?

Thank you very much for your kindness. We have pulse readings, timers, temperature controls and common triggers for motors and valves. They are equipment that are in use on the market and not a new project. Thank you one more time. Let's check out the STM8 family.

Sure but you're likely going to have to redesign a sub-section of the board to accommodate new parts to get equivalent functionality, there's not going to be a drop in replacement.

If a 28-pin DIP might be able to replicate with a module level implementation using modern SMT parts.

As Tesla said, there is in fact no replacement for such an old microcontroller, which was discontinued many years ago. Since then, there have been an extremely large number of further developments, so that a change to a newer platform is imperative.

However, with STM8, one should not rely on a family that is not significantly younger than the ST6 and will not be available in the foreseeable future. Instead, more modern mcu such as the STM32G030K6 or STM32G031K4 would be recommended, which can easily cover the functions of the plain old ST6.

If EEPROM is necessary, one could also take a look at the STM32L010K4 because of its EEPROM technology, but due to the current extremely high demand, it is probably better to use an STM32G0 and emulate EEPROM in flash there.

Good luck!
