Many industrial controllers do things based on very simple conditions such as sensor threshold activation or button press. Consequently 1-bit MPUs and MCUs found a unique niche use as [[programmable logic controller]]s | + | 1-bit MPUs and MCUs found some success in industrial equipment where actual calculations was not needed but simple Boolean operations dominated the majority of the task.

For general purpose applications and other calculations-related applications, 1-bit was largely seen as obsolete even in the early 1970s. Most bit-serial applications quickly switched over to {{arch|4|4}}/{{arch|8}} and then {{arch|16}} microprocessors, if not simply due to their low cost. Today all 1-bit microprocessors are largely obsolete, even in academia. | For general purpose applications and other calculations-related applications, 1-bit was largely seen as obsolete even in the early 1970s.
