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
