Selecting Supervisor IC

Hi
I plan to use 89C2051 uC along with my GSM module which is working at 3.8V DC. From the catalog of 89C2051, I understand that it can work at 3.8V. So I plan to set my DC voltage at 3.8V. But the supervisor IC (for resetting and supervising uC) available with me is DS1232 which require 5V DC.
If possible, I would like to use a single 3.8V DC supply. What can I do?

Dallas (as you probably know) is now maxim! There are literally hundreds of maxim derivatives on the supervisor circuits...You will need to go here..**broken link removed** and select the best one for your circuit.

I wish I could help further (I don't use them)

That is true. For small quantities, I usually buy from the market. Here this DS1232 is the one I could locate in the market. I could see supervisor ICs working at 3.8V in maxim site. But could not locate in shop. So thought of seeking the best method to use DS1232 itself.

On the .netmf boards they have an 800ma 5v reg and a 800ma 3,3v reg perhaps you can just do the same.
