1. Typical current at VDD = 2.4 V, 25 °C. for STOPx, SHUTDOWN and Standby, else VDD = 3.3 V, 25 °C.

2. The Flash memory controller can be placed in power-down mode if the RF subsystem is not in use and all the program is run from the SRAM.

3. The SRAM1 and SRAM2 clocks can be gated off independently.

4. HSE (32 MHz) automatically used when RF activity is needed by the RF subsystem.
