AN2286: Simulating a 555 Timer with PSoC

The PSoC Mixed-Signal Array is a versatile system-on-chip that facilitates complete system design. But can it do everything? It is a truth universally acknowledged, that any single circuit worthy of construction can be built with 555 timers. It follows that if the PSoC can simulate a 555 timer, then PSoC can be used to design any circuit of significance. Included in this Application Note is a brief history of the 555 timer. A PSoC device simulation is developed and examples of retro 555 timer applications are shown.
