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 SST55LD019M device supports

Multi-Level Cell (MLC) and high density Single-Level

Cell (SLC) 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 3 sec + 0.5 sec/GByte of drive capacity, allowing a

2 GByte flash drive to be fully initialized in about 4 seconds.

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.
