PRODUCT DESCRIPTION
The SST55VD020 is the heart of a high-performance,
flash media-based data storage system. The NAND Con-
troller recognizes the control, address, and data signals on
the ATA/IDE bus and translates them into memory
accesses for standard NAND-type flash media. Utilizing
both Single-Level Cell (SLC) and Multi-Level Cell
(MLC) flash media, this technology supports solid state
mass storage applications by offering new, expanded
functionality while enabling smaller, lighter designs with
lower power consumption.
The NAND Controller supports standard ATA/IDE protocol
with up to PIO Mode-6, Multi-word DMA Mode-4, and
Ultra DMA Mode-4 interface. The ATA/IDE interface is
widely used in such products as portable and desktop
computers, portable media player, music players, handheld
data collection scanners, PDAs, handy terminals, personal
communicators, audio recorders, monitoring devices, and
set-top boxes.
The NAND Controller uses SuperFlash memory technol-
ogy and is factory pre-programmed with an embedded
flash file system. Upon initial power-on, the SST55VD020
recognizes attached flash media devices, sets up a bad
block table, executes all necessary handshaking routines
for flash media support, and, finally, performs the low-level
format. This process typically takes about 3 second plus
0.5 seconds per gigabyte of drive capacity, allowing a 4
GByte flash drive to be fully initialized in about 5 seconds.
For added manufacturing flexibility, system debug, re-ini-
tialization, and user customization can be accomplished
through the ATA/IDE interface.
