I am thinking of using the CSS555/CSS555C timer IC in an upcoming project where I need a low power timer. Has anyone here used these and care to share their experiences? These are timers just like the classic 555 timer IC but they are extremely low power (even lower than the newer CMOS based 555 IC's) and can be programmed with an Uno based programmer as described here: Project hub link
Which version of the two IC's do you prefer (the C or non-C version) and why? The C version has the programmable capacitor in it. Even if you don't see the need for that capacitor, do you suggest still getting the C-version to have it down the road? Or is it better to go with the non-C version for some other aspects? Any input is welcome. Thank you!
