Notes:

Typical value measured during characterization at 3.3V and 25℃.

The test conditions are as follows:

– All GPIO except RPA3 are pulled up. RPA3 is pulled down.

– All peripherals are disabled (except EIC).

– All PB clocks are divided by 16.

– LPRC is set as LPCLK.

– SOSC is disabled.

– CLDO is configured at lowest possible voltage (VREG Trim = 0x07).

– PMU is configured to the Buck PSM mode on the Sleep Mode Entry with current sense is disabled.

– Cache is enabled and configured to wait states PFMWS[3:0] as 0xF.

– Backup RAM in the Retention mode.

– DSU is disconnected.

– RF system is in low power configuration.

– Entry to the Sleep mode is enabled and WFI instruction is executed.

– In XTAL ON mode - PMU Buck clock is derived from POSC 16 MHz and scaled to 1 MHz. FRC is OFF.

– In XTAL OFF mode - PMU is clocked from FRC and XTAL 16 MHz clock is disabled and clock

configuration in CRU changed to FRC.
