Its worth pointing out that the apparently miraculous 32uA/MHz energy efficiency only comes about as a result of an on-chip buck regulator stepping down the core voltage to 1-1.2V from a 3V supply. Also the lowest current draw per MHz comes when running from flash with umpteen wait-states @ 150MHz.

There is no SDIO device in the LPC551x/S1x family.

If you want something cheaper, I have been reading of the OKdo E1 iot board £13.42. Based on NXP LPC55S69 dual-core Cortex M33.
