PRODUCT DESCRIPTION
SST’s ATA Flash Disk Controller is the heart of a high-
performance, flash media-based data storage system.
The ATA Flash Disk Controller recognizes the control,
address, and data signals on the ATA/IDE bus and trans-
lates them into memory accesses to the standard NAND-
type flash media. The SST55LD019A/B/C device sup-
ports both Single Level Cell (SLC) and Multi-Level Cell
(MLC) flash media. This technology suits solid state
mass storage applications offering new, expanded func-
tionality 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. SST’s ATA Flash Disk
Controller supports standard ATA/IDE protocol with up to
PIO Mode-4 and Multi-word DMA Mode-2 interface.
Utilizing SST’s proprietary SuperFlash memory technology,
the ATA Flash Disk Controller is factory pre-programmed
with an embedded flash file system which, upon initial
Power-on, 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 seam-
less integration of flash drives into an embedded design.
For added manufacturing flexibility, system debug, re-ini-
tialization, and user customization can be accomplished
either through the ATA/IDE interface, for ATA Disk Module
or flash drive products, or through the Serial Communi-
cation Interface (SCI), for fully embedded ATA Flash Disk
Controller designs.
