I have seen some posts here about it but they all are talking about 5v supply voltage, I want to generate a 1 Hz square wave but my supply voltage is 3.3v , can someone guide me on how ?

The ICM7555 is a Cmos 555 made only by Intersil but the LMC555 is the same and is made by National Semi recently bought by Texas Instruments and the TLC555 is also the same and is also made by Texas Instruments. All three of them are sold today but the TLC555 costs less than the others.You can use 7555 for lower voltages(2V to 18V).
