Hi,

   

We have a design using the SPI master (2.5v) and other IPs (ADC, LCD, shift regs...). When the whole design is put in hibernate the power consumption stays too high (16mA) even if peripheral sleep functions are called.

   

When the SPI master IP is removed, the power consumption in hibernate mode is ok (~50uA).

   

Is there any issues regarding the SPI IP in hibernate mode ?

   

 

   

Thanks in advance

   

Best regards

   

Nicolas

Did you put the SPI's GPIO pins into High-Z mode?
