Does RESET meed a pull-up if using a DS1813?

Subject pretty much says it all.

The protoboard I'm making will assume you have a DS1813. If so, do I still need to put a pull-up resistor on the RESET line?

Thanks

No. As explained in the datasheet, the DS1813 includes an internal pullup resistor.

One thing to note is theDS1813's internal pullup is 5.5K.

Just to confirm, I am using the DS1813 in my project without an external pullup.

Thanks for the information.

Concerning the 5.5K pullup, I normally use 3.3K. That shouldn't be a problem, usually. Right?

Thanks

I use 3.3K as well and have not run into any issues with it.
