3. Introduction
3.1 General Description
The SAMSUNG MultiMediaCard is a universal low cost data storage and communication media. It is designed to cover a
wied area of applications as smart phones, cameras, organizers, PDAs, digital recorders, MP3 players, pagers, electronic
toys, etc. Targeted features are high mobility and high performance at a low cost price. It might also be expressed in terms
of low power consumption and high data throughput at the memory card interface.
The MultiMedaiCard communication is based on an advanced 13-pin bus. The communication protocol is defined as a
part of this standard and referred to as MultiMediaCard mode. For compatibility to existing controllers the cards may offer,
in addition to the MultiMediaCard mode, an alternate communication protocol which is based on the SPI standard.
The SAMSUNG MultiMediaCard is very small, removable flash storage devices, designed specifically for storage applica-
tions that put a premium on small form factor, low power and low cost. Flash is the ideal storage medium for portable, bat-
tery-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.
