PRODUCT DESCRIPTION

SST’s ATA flash disk controller is the heart of a high-perfor-

mance, flash media-based data storage system. The ATA

flash disk controller recognizes the control, address, and

data signals on the ATA/IDE bus and translates them into

memory accesses to the standard NAND-type flash media.

This technology suits solid state mass storage applications

offering new, expanded functionality while enabling smaller,

low power consuming, and lighter designs.

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.

Utilizing SST’s proprietary SuperFlash embedded memory

technology, The ATA flash disk controller is preprogrammed

with an embedded flash file system which, upon power-up,

recognizes the flash media devices and performs all the

necessary handshaking routines for flash media support.

This enables the product manufacturer a completely seam-

less integration of flash drive into an embedded design.

The ATA flash disk controller integrates an on-chip clock cir-

cuitry and Serial Communication Interface (SCI) for system

reset and user customization.

The SST55LD017A is a standard performance ATA

disk controller supporting capacities up to 128 MB.

SST55LD017B is a high-performance ATA disk con-

troller with sustained write performance up to 2.4 MB/

sec. SST55LD017C is a super high-performance ATA

disk controller with sustained write performance up to

4.0

SST55LD017C can support up to 5 flash media

devices directly for a maximum capacity of 640 MB. By

using an external decoder, the SST55LD017B and

SST55LD017C can support up to 16 flash media

devices for the equivalent capacity of 2 GB.

Users can select either an internal or external system clock

option for optimal performance vs. the supply current.

The ATA flash disk controller comes packaged in an indus-

try standard 100-lead TQFP package for easy integration

into an SMT manufacturing process. The ATA flash disk

controller also comes preprogrammed with a 10-byte

unique serial ID. For even greater system security and data

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

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

The controller also offers a WP_PD# pin to protect data

stored on flash media from unauthorized overwrites.
