Shall we enable BOD reset always?

Sun1998 — Thu, 08 Sep 2022 07:22:11 GMT

Recently we met a case that the code is lost during power on/off cycle on another brand MCU, this issue was solved by enabled BOD reset feature.

For LPC11xx series, I wonder, shall we must enable BOD reset? if without it, is there any risk losing the programmed code in flash?

PS: no IAP usage in this case, the FLASH is used as code ROM only.

BOD is used to prevent the circuit when the voltage drops unexpectedly for a very short time so as to avoid failure.

Whether or not to enable BOD depends on your external power supply circuit stability. LPC11xx has BOD. We can enable it if need.

Hope this helps,
