PRODUCT DESCRIPTION
SST’s ATA-Disk Module (ADM) 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 ADM is a solid state disk drive that is designed to
replace conventional IDE hard disk drive and can be
plugged into a standard IDE connector commonly found in
desktop or portable PC systems.
ADM has built-in microcontroller and file management
firmware that communicates with ATA standard inter-
faces; therefore, the ADM does not require additional or
proprietary host software such as Flash File System
(FFS) and Memory Technology Driver (MTD) software.
The ADM is designed to work at either 5V or 3.3V and is
available in 8 to 192 MByte capacities. It uses standard ATA
driver that is part of all major OS such as Windows 95/98/
2000/NT/CE, MAC, UNIX, etc.
All signals, except WP#, are in compliance with the ATA
specifications. WP# is used to write protect the information
stored on the ADM. The WP# could be connected to the
motherboard write protect control logic through a jumper.
When WP# is low, the ADM is write protected to prohibit
any inadvertent writes.
Every ADM 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 ADM integrates a standard 40- or 44-pin female
connector for easy and cost effective mounting on top
of a standard IDE male connector commonly found on
the system motherboards. ADM also offers user
selectable Master/Slave operation through an external
jumper setting.

Advance Information
1.0 GENERAL DESCRIPTION
The SST’s ATA-Disk Module (ADM) contains a controller,
embedded firmware, and Flash Media with a 40-pin or 44-
pin female connector. Refer to Figure 1-1 for SST’s ADM
block diagram. The controller interfaces with the host sys-
tem allowing data to be written to and read from the Flash
Media.
1.1.3 Power Management Unit (PMU)
Power Management Unit controls the power consumption
of the ADM. The PMU dramatically extends product battery
life by putting the part of the circuitry that is not in operation
into sleep mode.
1.1.4 SRAM Buffer
1.1 Performance-optimized ATA Controller
The heart of the ADM is the ATA controller which translates
standard ATA signals into Flash Media data and controls.
SST’s ADM contains a proprietary ATA controller specifi-
cally designed to attain high data throughput from host to
Flash. The following components contribute to the ATA con-
troller’s performance.
1.1.1 Microcontroller Unit (MCU)
The MCU translates ATA commands into data and control
signals required for flash memory operation.
1.1.2 Internal Direct Memory Access (DMA)
The ATA controller inside ADM uses DMA allowing instant
data transfer from buffer to memory. This implementation
eliminates microcontroller overhead associated with tradi-
tional, firmware based, memory control, increasing data
transfer rate.
A key contributor to the ATA controller performance is an
SRAM buffer. The buffer optimizes the data writes to Flash.
1.1.5 Embedded Flash File System
Embedded Flash File System is an integral part of the
SST’s ATM controller. It contains MCU Firmware that per-
forms the following tasks:
1. Translates host side signals into Flash Media
Writes and Reads.
2. Provides Flash Media wear leveling to spread the
Flash writes across all the memory address space
to increase the longevity of Flash Media.
3. Keeps track of data file structures.
1.1.6 Error Correction
The ATA Controller contains ECC algorithm that corrects 3
bytes of error per 512 Byte sector.
