Combined Power On Reset and Brown Out Reset
Key Benefits
- Ultra low power consumption in normal mode and in low power mode enabling to optimize the overall consumption of the Always-On-Domain
- Possibility to disable the BOR monitoring during low power mode in order to save power
- High programmability: POR and BOR thresholds are all programmable. BOR allows a dynamic programming to comply with the supply voltage of the power domain
