PRODUCT DESCRIPTION
SST’s ATA Flash Disk Controller is the heart of a high-per-
formance, flash media-based data storage system. The
ATA Flash Disk Controller recognizes the control, address,
and data signals on the ATA/IDE bus and translates them
into memory accesses to the standard NAND-type flash
media. This technology suits solid state mass storage appli-
cations offering new, expanded functionality while enabling
smaller, lighter designs with lower power consumption.
The ATA/IDE interface is widely used in such products as
portable and desktop computers, digital cameras, music
players, handheld data collection scanners, PDAs, handy
terminals, personal communicators, audio recorders, moni-
toring devices, and set-top boxes.
Utilizing SST’s proprietary SuperFlash memory technology,
the ATA Flash Disk Controller is factory preprogrammed
with an embedded flash file system which, upon initial
power-up, recognizes the attached flash media devices,
sets up a bad block table, executes all necessary hand-
shaking routines for flash media support, and, finally, per-
forms the low-level format. This process typically takes
about 0.5 sec/MB of drive capacity, allowing a 640 MByte
flash drive to be fully initialized in about 5 minutes.
This technology enables a very fast, completely seamless
integration of flash drives into an embedded design. For
added manufacturing flexibility, system debug, re-initializa-
tion, and user customization can be accomplished either
through the ATA/IDE interface, for ATA Disk Module or flash
drive products, or through the Serial Communication Inter-
face (SCI), for fully embedded ATA Flash Disk Controller
designs.
The SST55LD017D high-performance ATA Flash Disk
Controller offers sustained write performance up to 4.0
MB/sec. The SST55LD017D can directly support up to
5 flash media devices for up to 640 MB capacity or,
through simple decoding logic, can support up to 32
flash media devices for up to 4 GB capacity. Users can
select either an internal or external system clock option for
optimal performance vs. the supply current.
