These figures represent the power consumption typically measured on the power supplies..
Notes: 1. “Flash is in standby mode”, means the Flash is not accessed at all.
2. Low power consumption figures stated above cannot be guaranteed when accesing the Flash in Ultra Low
Power mode. In order to meet given low power consumption figures, it is recommended to either stop the
processor or jump to SRAM.
