1. The typical value is measured at VDD = 1.8 V. The maximum value is for 1.71 V ≤ VDD ≤ 3.6 V and is at VDD = 1.71 V in Run/Sleep mode

on SMPS.

IDD (Flash_Bank2)(1)

Flash bank 2 static consumption in

normal mode (PD2 = 1 vs. PD2 = 0)

IDD (Flash_Bank_LPM)(2)

One Flash bank additional static

consumption in normal mode

versus low-power mode (LPM = 0

vs. LPM = 1)

1. When flash memory is in power down in Sleep mode (SLEEP_PD=1), Bank 1 and Bank 2 are in power down.

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