Hi,
I was currently working on Hour meter with 4 digit display ,max hours 9999. Every time when meter gets supply It starts to count time ,& every after 1 minute It write to E2PROM [at24c01] to save the count.
My question is it correct decision to use 24cxx for this purpose , because it is possible to cross 1 million read write operations and may damage(?) E2PROM .
Is there any other technique for this.
Is 93c46 is better than 24cxx.

Thanks & Regards
