Standard reflow profiles for QFN apply;. ## Supply range and power-on reset The integrated brown-out detect and POR handles power-up sequencing and low-voltage lockout — no external supervisor needed for basic designs. The WDT peripheral adds a watchdog for unattended or safety-related applications.
