During the 40 years in which the 555 timer, 741 op-amp, and Exar XR-2209 have been in production, complete central processing units (CPUs) for digital computing have been developed in the form of microprocessors. Microprocessors have in some circumstances been used to create far more flexible control systems, with fewer parts than were available with the legacy, discrete, multiple-chip-based assemblies.

A microprocessor is a computer central processing unit in an IC chip format, while a microcontroller ...
