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.  
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.  
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.
