Multi Media Card Flash Memory card is a very small, removable flash storage device,
designed specifically for storage applications placing a premium on a
, low power and high performance. Multi Media Card is
an ideal storage medium for portable, battery-powered devices. It
extends system battery life because it is nonvolatile, requiring no
power to maintain the stored data. Multi Media Card also features low
power consumption and a wide operating range for temperature, shock and
vibration allowing for carefree, portable storage. Multi Media Card is
well suited to meet the needs of small, low power electronic devices
targeted at the consumer market (Such as Palm's, MP3 devices, Digital
Cameras etc. The small form factor and cost meet the miniaturization
needs and low retail price requirements. With a form factor of 32mm high
by 24mm wide and 1.4mm thick, it is the ideal size for small, thin
portable devices, such as pagers and phones. This form factor is part of
a new, emerging, proposed open standard. In order to support this wide
range of applications, the Multi Media Card interface protocol is
designed for maximum scalability and configurability. All device and
interface configuration data (e.g. maximum frequency, supported modes of
operation, memory size, card ID, etc.) will be stored on the Multi Media
Card. A high performance 7 pin serial interface (SPI) allows for easy
integration into any design, regardless of microprocessor utilized.
