PRODUCT DESCRIPTION
The NAND Controller 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 to the standard NAND-type flash media. The
SST55VD031 device supports Single-Level Cell (SLC)
and Multi-Level Cell (MLC) flash media. This technol-
ogy is ideal for solid-state mass storage applications offer-
ing, 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, multi-
media players, music players, handheld data collection
scanners, PDAs, handy terminals, personal communica-
tors, audio recorders, monitoring devices, global positioning
systems, and set-top boxes. The SST NAND Controller
supports standard ATA/IDE protocol with up to PIO Mode-
6, Multi-word DMA Mode-4, and Ultra DMA Mode-5
interface.
The NAND Controller uses SST proprietary SuperFlash
memory technology and is factory pre-programmed with
an embedded flash file system. Upon initial power-on, the
NAND Controller recognizes attached flash media
devices, sets up a bad block table, executes all necessary
handshaking routines for flash media support, and per-
forms the low-level format.
The entire set up process typically takes about 3 sec plus
0.5 sec for each GByte of drive capacity. A 16 GByte flash
drive is fully initialized in about 11 seconds.
