1. Evaluated by characterization. Not tested in production.

2. When one bank is in power-down, this consumption is saved. When the flash memory is in power down in Sleep mode (SLEEP_PD =1 ), Bank 1 and Bank 2 are in

power down.

3. If no bank is in power-down, the flash memory additional static consumption in normal mode versus low-power mode is 2 x IDD(Flash_Bank_LPM).
