RS-MMC卡標準

RS-MMC卡標準:small, removable flash storage devices, designed specifically for storage applications that
put a premium on small form factor, low power and low cost. Flash is the ideal storage
medium for portable, battery-powered devices. It features low power consumption and is
non-volatile, requiring no power to maintain the stored data. It also has a wide operating
range for temperature, shock and vibration.
The MultiMediaCard and RS-MultiMediaCard are well suited to meet the needs of small,
low power, electronic devices. With form factors of 32 mm x 24 mm and 1.4 mm thick for
the MultiMediaCard and 18 mm x 24 mm x1.4 mm for the RS-MultiMediaCard, these
cards can be used in a wide variety of portable devices like mobile phones, and voice
recorders.
To support this wide range of applications, the MultiMediaCard Protocol, a simple sevenpin
serial interface, is designed for maximum scalability and configurability. All device and
interface configuration data (such as maximum frequency, card identification, etc.) are
stored on the card.
