SDIO Simplified Specification Version 2.00

13. SDIO Physical Properties

This chapter is not included in the Simplified Specification.

13.1SDIO Form Factors

The SDIO definition encompasses different form factors:

•Full-Size SDIO — compatible with host sockets designed for SD memory cards

•miniSDIO — compatible with host sockets designed for miniSD memory cards

13.2Full-Size SDIO

The SDIO card is compatible with host sockets designed for SD memory cards. In addition, the SDIO cards can be extended to allow for external connectors, antennas etc. With the exception of the write protect switch, all SDIO cards shall meet the mechanical specifications described in the SD Physical Specification for that portion of the card that is not extended. The WP switch is not supported by hosts for SDIO only cards.

The rest of this section is not included in the Simplified Specification.

13.3miniSDIO

The miniSDIO card is compatible with host sockets designed for miniSD memory cards. In addition, the miniSDIO cards can be extended to allow for external connectors, antennas etc. All miniSDIO cards shall meet the mechanical specifications described in miniSD Card Addendum Version 2.00, Part 1 Physical Layer Specification Version 2.00 for that portion of the card that is not extended.

When a miniSDIO card is inserted into a miniSD to SD memory card adaptor, and plugged-into an SDIO host slot, it shall appear to the host as an SDIO card.

The rest of this section is not included in the Simplified Specification.

14. SDIO Power

14.1SDIO Card Initialization Voltages

SDIO Version 2.00 eliminate the voltage range 2.0-2.7V for basic communication because the SD Physical Specification Version 2.00 eliminates it. SDIO cards follow the same voltage and current requirements as SD memory cards. This means that an SDIO or combo card shall be used at an operating voltage range of 2.7 to 3.6V. The hosts shall not supply the voltage range 2.0-2.7V for basic communication to the SDIO Version 2.00 cards.

14.2SDIO Power Consumption

The SDIO cards are intended to operate in mobile devices that have limited power sources available. Because the host’s battery life may be significantly reduced if the SDIO card draws excessive power, a primary goal of SDIO designers should be low power. By reducing power consumption to a minimum, Host battery life and consumer satisfaction will be enhanced. The following power data represents the maximum that a SDIO card may draw. It is important for designers to note that a low power host may reject any SDIO card that identifies
