Features
Rev 1.1
TS128MMC ~ TS2GMMC is a 128MB ~ 2GB
MultiMediaCard. It’s a highly integrated with flash
memory, and is accessed via a dedicated serial
interface optimized for fast and reliable data
transmission. It is 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.
