Porst tc297

hi guys
I would like to design a new PCB with a TC297. A requirement is to keep it as simple as possible. Now my Question, is it possible to connect the PORST only with a pull-up to Power supply (It's not requested to use a extern PORST), without any other Voltage observation devices like WD or reset Signals. I have reservations doing this and would like to know what I need to take into consideration..??

Re: Porst tc297

It is recommended to monitor externally all supplies generated external to the microcontroller and to assert PORST reset pin in case of violation of the lowest operational limits.
