Abstract: Application Note AN2286 AN2286 Simulating a 555 Timer with PSoCTM Author: Dave Van Ess Associated , 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. Introduction The 555 timer IC was first introduced in 1971 by the Signetics Corporation and called the "The ... Original
