About iSDIO

iSDIO (intelligent SDIO) is an SD Association standard used to control advanced SD memory cards, such as FlashAir.

Specifically, iSDIO is a process for passing commands back and forth between SD cards and host devices, based on specifications provided by "Addendums".

For example, FlashAir is compliant with the "Wireless LAN Addendum".

A simplified version of the iSDIO specification is available for download from the SD Association.
