PRODUCT DESCRIPTION
The SST85LD0128, SST85LD0256, and SST85LD0512
NANDrive™ integrated circuits (IC) are high-performance,
fully-integrated, embedded flash solid state drives. They
combines an integrated ATA Controller and a 128/256/512
MB NAND Flash die in a multi-chip package. These
products are well suited for solid state mass storage
applications offering new and expanded functionality while
enabling cost effective designs.
The NANDrive provides complete IDE Hard Disk Drive
functionality and compatibility in the industry’s smallest
12mmx18mm BGA package for easy, space saving, and
cost effective mounting to a system motherboard. It is a
perfect solution for portable, consumer and OEM,
electronic products requiring smaller and more reliable data
storage.
The SST85LD0128/0256/0512 NANDrive devices offer
added security protection for confidential information stored
in the flash media. They allow up to four protection zones
which can be set by the user to be Read-only or Hidden
(Read-disabled). The SST85LD0128/0256/0512 accesses
data within the protected zones through a password-
protected command. The NANDrive also provides a
WP_PD# pin to protect critical information stored in the
flash media from unauthorized overwrites.
ATA-based solid state mass storage technology is widely
used in such products as portable and desktop
computers, digital cameras, music players, handheld
data collection scanners, cellular phones, PCS phones,
PDAs, handy terminals, personal communicators,
advanced two-way pagers, audio recorders, monitoring
devices, and set-top boxes. SST NANDrive IC supports
standard ATA/IDE protocol with up to PIO Mode-4 and
Multi-word DMA Mode-2 interface.
The NANDrive devices come pre-programmed with a 10-
byte unique serial ID. For even greater system security, the
user has the option of programming an additional 10 Bytes
of ID space to create a unique, 20-byte ID. Additionally, the
capacity of the NANDrive products can be easily expanded
by connecting discrete NAND flash components through
the external Media bus.
The NANDrive is a single device, solid state drive that is
designed for embedded systems using standard ATA/IDE
protocol. It has built in microcontroller and file management
firmware that communicates with ATA standard interfaces;
therefore, the device does not require additional or
proprietary software such as Flash File System (FFS) and
Memory Technology Driver (MTD) software.
