ESMMC64 Datasheet, PDF (1/8 Pages) Eorex Corporation – 64MB/128MB/256MB/512MB MultiMediaCard™

64MB/128MB/256MB/512MB MultiMediaCard^TM
Description
ESMMC64 / ESMMC128 /
ESMMC256 / ESMMC512 are 64MB
up to 512MB MultiMediaCard^TM. These
are the highly integrated flash memory
with serial and random accessible via a
dedicated serial interface optimized for fast
and reliable data transmission. They are
fully compatible to a new consumer
standard, called the MultiMediaCard^TM
system standard defined in the
MultiMediaCard^TM system specification.
The MultiMediaCard^TM system is a new
mass-storage system based on innovations
in semiconductor technology. It has been
designed to provide an inexpensive,
mechanically robust storage medium in
card form for multimedia consumer
applications and mobile devices (handheld
PCs, digital cameras, MP3 players, etc.) to
store, copy, and move information like a
small hard drive.
