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?
