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
SST55LD040M device supports Single-Level Cell
(SLC) and Multi-Level Cell (MLC) flash media. This
technology is ideal for solid-state mass storage applica-
tions offering, 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-
4, Multi-word DMA Mode-2, and Ultra DMA Mode-6
interface.
