PRODUCT DESCRIPTION

SST’s ATA Flash Disk Controller is the heart of a high-

performance, flash media-based data storage system.

The ATA Flash Disk Controller recognizes the control,

address, and data signals on the ATA/IDE bus and trans-

lates them into memory accesses to the standard NAND-

type flash media. The SST55LD019A/B/C device sup-

ports both Single Level Cell (SLC) and Multi-Level Cell

(MLC) flash media. This technology suits solid state

mass storage applications offering new, expanded func-

tionality 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, music

players, handheld data collection scanners, PDAs, handy

terminals, personal communicators, audio recorders, moni-

toring devices, and set-top boxes. SST’s ATA Flash Disk

Controller supports standard ATA/IDE protocol with up to

PIO Mode-4 and Multi-word DMA Mode-2 interface.

Utilizing SST’s proprietary SuperFlash memory technology,

the ATA Flash Disk Controller is factory pre-programmed

with an embedded flash file system which, upon initial

Power-on, recognizes the attached flash media devices,

sets up a bad block table, executes all necessary hand-

shaking routines for flash media support, and, finally, per-

forms the low-level format. This process typically takes

about 0.5 sec/MB of drive capacity, allowing a 640 MByte

flash drive to be fully initialized in about 5 minutes.

This technology enables a very fast, completely seam-

less integration of flash drives into an embedded design.

For added manufacturing flexibility, system debug, re-ini-

tialization, and user customization can be accomplished

either through the ATA/IDE interface, for ATA Disk Module

or flash drive products, or through the Serial Communi-

cation Interface (SCI), for fully embedded ATA Flash Disk

Controller designs.

ATA Flash Disk Controller

SST55LD019A / SST55LD019B / SST55LD019C

Advance Information

The SST55LD019A/B/C high-performance ATA Flash

Disk Controller offers sustained write performance up to

10.0 MB/sec. The SST55LD019A controller is to be used

when the random access performance needs to be maxi-

mized. The SST55LD019B controller is to be used when

the sequential access performance needs to be maxi-

mized. The SST55LD019C controller is to be used when

the flash drive capacity and sequential access perfor-

mance need to be maximized. The SST55LD019A/B/C

can directly support up to 8 flash media devices or,

through simple decoding logic, can support up to 255

flash media devices. Users can select either an internal

or external system clock option for optimal performance vs.

the supply current.

The SST55LD019A/B/C offers added security protection

for confidential information stored in the flash media. It

allows up to four protection zones which can be set by the

user to be Read-only or Hidden (Read-disabled). The ATA

Flash Disk Controller can access the data within the pro-

tected zones through a password-protected command.

The controller also provides a WP_PD# pin to protect criti-

cal information stored in the flash media from unauthorized

overwrites.

The ATA Flash Disk Controller comes pre-programmed

with a 10-byte unique serial ID. For even greater system

security, the user has the option of programming an addi-

tional 10 Bytes of ID space to create a unique, 20-byte ID.

The ATA Flash Disk Controller comes packaged in an

industry-standard, 100-lead TQFP package, an 84-ball

TFBGA package, or a 64-lead TQFP package (reduced

function) for easy integration into an SMT manufacturing

process.

ATA Flash Disk Controller

SST55LD019A / SST55LD019B / SST55LD019C

Advance Information

1.0 GENERAL DESCRIPTION

The ATA Flash Disk Controller contains a microcontroller

and embedded flash file system integrated in TQFP and

TFBGA packages. Refer to Figure 2-1 for the ATA Flash

Disk Controller block diagram. The controller interfaces with

the host system allowing data to be written to and read

from the flash media.

1.1.5 Embedded Flash File System

The embedded flash file system is an integral part of the

ATA Flash Disk Controller. 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 across all unused memory

address space 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)

The ATA Flash Disk Controller utilizes 72-bit Reed-

Solomon Error Detection Code (EDC) and Error Correc-

tion Code (ECC), which provides the following error

immunity for each 512-byte block of data:

1. Corrects up to three random 12-bit symbol errors.

2. Corrects single bursts up to 25 bits.

3. Detects single bursts up to 61 bits and double

bursts up to 15 bits.

4. Detects up to six random 12-bit symbol errors.

1.1.7 Serial Communication Interface (SCI)

The Serial Communication Interface (SCI) is designed to

enable the user to restart the self-initialization process and

to customize the drive identification information.

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.

1.1 Performance-optimized ATA Flash Disk

Controller

The heart of the flash drive is the ATA Flash Disk Controller

which translates standard ATA signals into flash media data

and control signals. The following components contribute to

the ATA Flash Disk Controller’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 ATA Flash Disk Controller uses internal DMA allowing

instant data transfer from buffer to flash media. This imple-

mentation 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 consump-

tion of the ATA Flash Disk Controller. The PMU dramatically

reduces the power consumption of the ATA Flash Disk

Controller 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 ATA Flash Disk Controller perfor-

mance is an SRAM buffer. The buffer optimizes the host’s
