About the iSDIO Standard

The intelligent SDIO standard that reduces the actual load on SD host devices

The iSDIO (intelligent SDIO) standard was developed to enable the use of a wide range of functions, such as wireless LAN, TransferJet and other communication technologies, with simple commands issued by SD host devices.
The main feature of the iSDIO standard is that data can be transferred directly between flash memory modules and function modules via the card controller stored on SD cards without having to go through the host. This enables high-speed data transfer without having to rely on the data transfer performance of the host device.

SDA is standardizing the Wireless LAN SD standard and the TransferJet SD standard.
