Hello I'm looking for microcontroller supporting 7 external interrupt because I have to replace SAB80C535. All microcontroller with I've found have 2 external interrupt, unfortunately it's not enough for the device in which SAB80C535 is placed. Do you know what microcontroller (based on 8051) model is able to handle so many external interrupts?
I know of none; however quite a few (some SiLabs, NXP) have a port match interrupt, that, with a bit of code, can be used as 8 separate interrupts
