PRODUCT DESCRIPTION

The SST85LD1001K, SST85LD1002L and

SST85LD1004M NANDrive™ integrated circuits (IC) are

high-performance, fully-integrated, embedded flash solid

state drives. They combine an integrated ATA Controller

and either 1GByte, 2GByte, or 4GByte of NAND Flash in a

multi-chip package. These products are ideal for 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 SST85LD1001K/1002L/1004M 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.

NANDrive IC is available with advanced NAND

management technology, a NAND memory management

technology that enhances data security, significantly

improves endurance, and accurately predicts the minimum

life span of NAND flash devices. Advanced NAND

management technology combines NAND controller

hardware error correction, advanced wear leveling

algorithms, and bad block management to extend the life of

the product.

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 flash media wear leveling to spread the

flash writes across all memory address space to

increase the longevity of flash media.

3. Keeps track of data file structures.

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 access to

the SCI interface in the 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.

1.3 Advanced NAND Management

Technology

Advanced NAND management technology balances the

wear on erased blocks with an advanced wear-leveling

scheme which provides a minimum of 10 million product

write cycles. Advanced NAND management technology

tracks the number of program/erase cycles within a group.

When the host updates data, higher priority is given to the

less frequently written erase blocks; thereby, evenly

distributing host writes within a wear-leveling group.

Advanced NAND management technology enhances

NANDrive security with password protection and four

independent protection zones which can be set to Read-

only or Hidden.

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

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

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 access to the SCI interface in the PCB design to

aid in design validation.

7.0 LIFETIME EXPECTANCY

NANDrive is available with two endurance options—

standard NANDrive and NANDrive with advanced NAND

management technology.

7.1 Standard NANDrive

NANDrive provides minimum endurance of 10,000

program/erase cycles. The extensive ECC and wear-

leveling algorithms utilized in the NANDrive extend the

typical life of the product beyond the guaranteed minimum

endurance of the NAND flash.

7.2 NANDrive with Advanced NAND Man-

agement Technology

NANDrive with advanced NAND management technology

significantly extends the life of a product with its extensive

ECC, advanced wear-leveling, and data scan and Refresh

(DSR) algorithms. Each NANDrive device is partitioned

into four wear-leveling groups. See Table 4-4 for the group

size of each product.

Each NANDrive wear-leveling group can receive at least 10

million write cycles from the host. With four wear-leveling

groups in each product, 40 million write cycles per product

is possible when host writes are evenly distributed across

groups.

For applications where data security is essential, NANDrive

with advanced NAND management technology offers two

additional protection features—protection zones and

password protections.
