Would brown-out affect IWDG?

Question asked by winix on Apr 7, 2016
Hi all, we am using STM32F051K8 MCU, and we have the IWDG started and feed the dog regularly to keep everything happy.  However, we found that the system could possibly suffer brown out mostly when battery is running very low. This brown-out could be the cause of frozen MCU in an unknown state.

Question is, STM32F051K8 do not have BOR, but is it possible for the IWDG to be affected by BOR?
