Hi @dylanou ,

Thanks for your interest in STSAFE-A110 solution.

The X-CUBE-SAFEA1 package offer the StSafeA_Hibernate() function to set the STSAFE-A110 in low power.

Be aware that when you are setting the STSAFE-A in hibernate mode, you have to select the wake up condition.

could be Reset pin only or (Reset pin or I2C Start condition)

In the case of wake up with I2C Start condition, be aware that any I2C communicate on the I2C bus will wake up the STSAFE-A.

To use the Reset pin, you need of course a layout that supports it.

Best Regards,

Benjamin
