It’s on a sub$ part with 8-20 pins and is intended to do what you might otherwise do with a handful of logic gates, for reasons of timing or power consumption.

It’s on a sub$ part with 8-20 pins and is intended to do what you might otherwise do with a handful of logic gates, for reasons of timing or power consumption. It’s also quite fast compared to the processor in this case. It’s great for handling basic state machine or logic tasks without waking the cpu unless it is needed. It replaces glue logic better than a straight microcontroller… I can imagine a lot of situations where you might install one as universal logic and not even bother to run code on the MCU… like universal glue logic with a built in MCU in case you need it, rather than the other way around.
