DS1307 equivalent for 3.3v ?

[aliyesami]

I got DS1337 but I overlooked the detail that this chip does not have any battery backup .
so which chip can i use instead of DS1307 since this chip doesnt work with 3.3v ?

thanks

I usually make a query on search engine from suppliers to give other options.
Take a look here and check for options from Microchip and Texas Instruments:
