They have so many, which is the best and easiest to interface chip in their list?

Hi Steven,

Pick the "cheapest one" or as the correct saying "least expensive" one.

How would you determine which one is easier to interface?

Based on what criteria?

Hi Paxmowa,

I have used the DS1337 on numerous projects. There have been previous posts on this forum that have listed the code for using this chip. It uses the I2C protocol. It is very important that you get a crystal with a 6pf load. The use of any other crystal will result in the time not staying correct. This chip only costs a couple of dollars and the crystal was less than a dollar from Digi-Key.

Yes Maxim has many types of RTC's. You have to select one that will work for your application.
