Dear NXP,

we are currently trying to verify the power consumption of the LPC54606 and are seeing something not quite in line with the datasheets.

 

At 1.85V supply

  • Measured deep sleep ~ 200uA (should 23uA according to the spec)

 

We need to further reduce the power consumption.

Seems internal flash memory is in standby mode when deep sleep.  Wondering how to power down the internal flash memory to further reduce the power consumption? Or other suggestion?
