SST’s ATA-Disk Chip (ADC) is a low cost, high perfor-
mance, embedded flash memory data storage system.
This product is well suited for solid state mass storage
applications offering new and expanded functionality
while enabling cost effective designs.
The ADC is a solid state disk drive that is designed to
replace conventional IDE hard disk drive and uses
standard ATA/IDE protocol. It has built in
microcontroller and file management firmware that
communicateswithATAstandardinterfaces;therefore,
the ADC does not require additional or proprietary
software such as Flash File System (FFS) and Memory
Technology Driver (MTD) software.
ATA-based solid state mass storage technology is
widely used in such products as portable and desktop
computers, digital cameras, music players, handheld
datacollectionscanners,cellularphones,PCSphones,
PDAs, handy terminals, personal communicators, ad-
vanced two-way pagers, audio recorders, monitoring
devices, and set-top boxes.
The ADC is designed to work at either 5V±10% or 3.3V
±5%. Thepinassignmentisdesignedtomatchexisting
IDE signaltraces on the motherboard. It uses standard
ATA driver that is part of all major OS such as Windows
95/98/2000/NT/CE, MAC, UNIX, etc.
ADC provides complete IDE Hard Disk Drive function-
ality and compatibility. ADC is a perfect solution to
consumer electronic products requiring smaller, but
more reliable and cost effective data storage. The ADC
is read and written using a single power supply of 5.0-
Voltsor3.3-Voltsandisavailablein8,16,24,32,48and
64 MByte capacities.
The ADC is packaged in the standard 600 mil. 32-pin
DIPpackageforeasyandcosteffectivemountingtothe
