PRODUCT DESCRIPTION
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.
dard interfaces; therefore, the ADC does not require addi-
tional or proprietary software such as Flash File System
(FFS) and Memory Technology Driver (MTD) software.
The ADC is designed to work at either 5V ±10% or 3.3V
±5%. The pin assignment is designed to match existing
IDE signal traces 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.
ATA-based solid state mass storage technology is widely
used in such products as portable and desktop computers,
digital cameras, music players, handheld data collection
scanners, cellular phones, PCS phones, PDAs, handy termi-
nals, personal communicators, advanced two-way pagers,
audio recorders, monitoring devices, and set-top boxes.
All signals, except WP#, are in compliance with the ATA
specifications. WP# is used to write protect the information
stored on the ADC. The WP# can be either connected to
motherboard write protect control logic or a jumper. When
WP# is low, the ADC is write protected to prohibit any inad-
vertent writes.
ADC provides complete IDE Hard Disk Drive functionality
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 to
using a single power supply of 5.0-Volts or 3.3-Volts and is
available in 8 to 192 MByte capacities.
Every ADC comes with factory-programmed, 20-Byte long,
unique identification number for extended data protection.
This feature prevents unauthorized duplication by allowing
encryption of customer data.
The ADC is a solid state disk drive that is designed to
replace conventional IDE hard disk drive and uses stan-
dard ATA/IDE protocol. It has built in microcontroller and file
management firmware that communicates with ATA stan-
The ADC is packaged in the 600 mil 32-pin DIP package
for easy and cost effective mounting to the system mother-
board.
