Figure 45-15. Measurement Setup for Configurations C and D
Note:
No current is drawn on VDDIN power input in Backup mode. The pin VDDIN can be left unpowered in Backup
mode.
45.7.2 Wait Mode Current Consumption
Wait mode configuration and measurements are defined in
Section 45.7.2.1 “Wait Mode Configuration”
.
Reminder: In wait mode, the core voltage regulator is on, but the device is not clocked. Flash power mode can be either
in stand-by mode or deep power-down mode. Wait mode provides a much faster wake-up compared to backup mode.
45.7.2.1 Wait Mode Configuration
32.768 kHz Crystal Oscillator running.
Fast RC Oscillator, Main Crystal and PLLs Stopped.
RTC running.
RTT enabled on 1 Hz mode.
Core BOD Enabled.
One wake-up pin (WKUPx) used in Fast Wake-up mode.
Anti-Tamper Input TMP0, TMP1, TMP2, TMP3 and RTCOUT0 enabled.
System IO Lines PA30, PA31, PB[0...3] in GPIO Input Pull-up Mode.
PLC in shutdown.
All other GPIO Lines in default state.
