PRODUCT DESCRIPTION
The SST85LD0512, SST85LD1001T and
SST85LD1002U NANDrive™ integrated circuits (IC) are
high-performance, fully-integrated, embedded flash solid
state drives. They combine an integrated ATA Controller
and either 512 MByte, 1 GByte, or 2 GByte of NAND Flash
in a multi-chip package. These products are ideal for
industrial grade solid state mass storage applications
offering new and expanded functionality while enabling
cost effective designs.
ATA-based solid state mass storage technology is widely
used in portable and desktop computers, digital
cameras, music players, handheld data collection
scanners, cellular phones, PCS phones, PDAs, handy
terminals, personal communicators, robotics, audio
recorders, monitoring devices, and set-top boxes.
SST NANDrive is a single device, solid state drive
designed for embedded ATA/IDE protocol systems and
supports standard ATA/IDE protocol with up to PIO Mode-
6, Multi-word DMA Mode-4 and Ultra DMA Mode-4
interface. The built in microcontroller and file management
firmware communicates with ATA standard interfaces;
thereby eliminating the need for additional or proprietary
software such as Flash File System (FFS) and Memory
Technology Driver (MTD) software.
The SST85LD0512 / SST85LD1001T / SST85LD1002U
NANDrives provide complete IDE Hard Disk Drive
functionality and compatibility in a 12mm x 24mm BGA
package for easy, space saving mounting to a system
motherboard. It is a perfect solution for portable, consumer
electronic products requiring smaller and more reliable data
storage.
The NANDrive provides a WP#/PD# pin to protect critical
information stored in the flash media from unauthorized
overwrites.
The NANDrive is 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.

1.0 GENERAL DESCRIPTION
Each NANDrive contains an integrated ATA Controller and
one or more NAND Flash dice in a LBGA package. Refer
to Figure 2-1 for the NANDrive block diagram.
1.1 Performance-optimized NANDrive
The heart of the NANDrive is the ATA Flash Disk Controller
which translates standard ATA signals into flash media data
and control signals. The following components contribute to
the NANDrive’s operation.
1.1.1 Microcontroller Unit (MCU)
The MCU translates ATA/IDE commands into data and
control signals required for flash media operation.
1.1.2 Internal Direct Memory Access (DMA)
The NANDrive uses internal DMA allowing instant data
transfer from buffer to flash media. This implementation
eliminates microcontroller overhead associated with the
traditional, firmware-based approach, thereby increasing
the data transfer rate.
1.1.3 Power Management Unit (PMU)
The power management unit controls the power
consumption of the NANDrive. The PMU dramatically
reduces the power consumption of the NANDrive by
putting the part of the circuitry that is not in operation into
sleep mode.
1.1.4 SRAM Buffer
A key contributor to the NANDrive performance is an
SRAM buffer. The buffer optimizes the host’s data transfer
to and from the flash media.
1.1.5 Embedded Flash File System
The embedded flash file system is an integral part of the
NANDrive. It contains MCU firmware that performs the
following tasks:
1. Translates host side signals into flash media
writes and reads.
2. Provides dynamic flash media wear leveling to
spread the flash writes to increase the longevity of
flash media.
3. Keeps track of data file structures.
4. Manages system security for the selected
protection zones.

1.1.6 Error Correction Code (ECC)
High performance is achieved through optimized hardware
error detection and correction.
1.1.7 Serial Communication Interface (SCI)
The Serial Communication Interface (SCI) is designed for
manufacturing error reporting. Always provide SCI interface
access to PCB design to aid in design validation.
1.1.8 Multi-tasking Interface
The multi-tasking interface enables fast, sustained write
performance by allowing concurrent Read, Program, and
Erase operations to multiple flash media devices.
1.2 NAND Flash
The NANDrive family utilize standard NAND Flash for data
storage.

3.0 PIN ASSIGNMENTS
The signal/pin assignments are listed in Table 3-1. Low
active signals have a “#” suffix. Pin types are Input, Output,
or Input/Output. Signals whose source is the host are
designated as inputs while signals that the NANDrive
sources are outputs.
The NANDrive functions in ATA mode, which is compatible
with IDE hard disk drives.

4.0 CAPACITY SPECIFICATION
Table 4-1 shows the default capacity and specific settings for heads, sectors, and cylinders. Users can change the
default settings in the drive ID table using the Identity-Drive command. If the total number of bytes is less than the
default, the remaining space could be used as spares to increase the flash drive endurance. It should also be noted that
if the total flash drive capacity exceeds the total default number of bytes, the flash drive endurance will be reduced.

5.0 CONFIGURABLE WRITE PROTECT/
POWER-DOWN MODES
The WP#/PD# pin can be used for either Write Protect
mode or Power-down mode, but only one mode is active at
any time. Either mode can be selected through the host
command, Set-WP#/PD#-Mode.
Once the mode is set with this command, the device will
stay in the configured mode until the next time this
command is issued. Power-off or reset will not change the
configured mode.
5.1 Write Protect Mode
When the device is configured in the Write Protect mode,
the WP#/PD# pin offers extended data protection. This
feature can be either selected through a jumper or host
logic to protect the stored data from inadvertent system
writes or erases, and viruses. The Write Protect feature
protects the full address space of the data stored on the
flash media.
In the Write Protect mode, the WP#/PD# pin should be
asserted prior to issuing the destructive commands: Erase-
Sector, Format-Track, Write-DMA, Write-Multiple, Write-
Multiple-without-Erase, Write-Sector(s), Write-Sector-
without-Erase, or Write-Verify. This will force the NANDrive
to reject any destructive commands from the ATA interface.
All destructive commands will return 51H in the Status
register and 04H in the Error register signifying an invalid
command. All non-destructive commands will be executed
normally.
5.2 Power-down Mode
When the device is configured in the Power-down mode, if
the WP#/PD# pin is asserted during a command, the
NANDrive completes the current command and returns to
the standby mode immediately to save power. Afterwards,
the device will not accept any other commands. Only a
Power-on Reset (POR) or hardware reset will bring the
device to normal operation with the WP#/PD# pin de-
asserted.
6.0 POWER-ON INITIALIZATION AND
CAPACITY EXPANSION
NANDrive is self-initialized during the first power-up. As
soon as the power is applied to the NANDrive it reports
busy for typically up to five seconds while performing bad
blocks search and low level format. This initialization is a
one time event.
During the first self-initialization, the NANDrive firmware
scans all connected flash media devices and reads their
device ID. If the device ID matches the listed flash media
devices, the NANDrive performs drive recognition based
on the algorithm provided by the flash media suppliers,
including setting up the bad block table, executing all the
necessary handshaking routines for flash media support,
and, finally, performing the low-level format.
If the drive initialization fails, and a visual inspection is
unable to determine the problem, SST provides a
comprehensive interface for manufacturing flow debug.
This interface not only allows debug of the failure and
manual reset of the initialization process, but also allows
customization of user definable options.
6.1 ATA/IDE Interface
The ATA interface can be used for NANDrive
manufacturing support. SST provides an example of a
DOS-based solution (an executable routine) for
manufacturing debug and rework.
6.2 Serial Communication Interface (SCI)
For additional manufacturing flexibility, the SCI bus can be
used for manufacturing error reporting. The SCI consists of
3 active signals: SCIDOUT, SCIDIN, and SCICLK. Always
provide SCI interface access to PCB design to aid in
design validation.
7.0 LIFETIME EXPECTANCY
NANDrive provides minimum endurance of 100,000 or
10,000 (as indicated by endurance sub-block of part
number) program/erase cycles and 10 year data retention
as stated by the selected NAND Flash components. The
extensive ECC and wear leveling algorithms utilized in the
NANDrive extend the life of the product.
