50.9.1 Backup Mode Current Consumption

Backup mode configurations and measurements are defined as follows:

  • Configuration A and B are typical use cases with crystal oscillator, anti-tamper pins enabled
  • Configuration C is the same as Configuration B, but with SLCD enabled
Remember: In Backup mode, the core voltage regulator is off and thus all the digital functions powered by VDDCORE are off. The 32 kHz Slow RC oscillator is an always-on clock source.
