SILICONDRIVE 2.5" DRIVE
SSD-DXXX(I)-3600
OVERVIEW
FEATURES
The SiliconDrive 2.5" Drive is an optimal
time-to-market replacement for hard
drives and flash cards or in host systems
that require low power and scalable
storage solutions.
• RoHS 6 of 6 compliant
• Integrated PowerArmor and SiSMART
technologies
• Capacity range: 128MB to 16GB
• Supports both 8-bit and 16-bit data
register transfers
SiliconDrive technology is engineered
exclusively for the high performance, high
reliability, and multiyear product lifecycle
requirements of the Enterprise System
• Supports dual-voltage 3.3V or 5V
interface
OEM
market.
Typical
end-market
14
• Data reliability <1 error in 10 bits read
applications include broadband data and
voice networks, military systems, flight
system avionics, medical equipment,
• MTBF 4,000,000 hours
• ATA-3 compliant
industrial
control
systems,
video
• Industry standard 2.5" Drive form factor
surveillance, storage networking, VoIP,
wireless infrastructure, and interactive
kiosks.
• Supports PIO modes 0-4 and DMA
modes 0-2
Every SiliconDrive is integrated with
SiliconSystems’ patented PowerArmor
and
patent-pending
SiSMART
technologies to virtually eliminate storage
systems failures.
PowerArmor prevents data corruption and
loss from power disturbances by
integrating patented technology into every
SiliconDrive.
16GB
SSD-D16G(I)-3600
SiSMART acts as an early warning system
to eliminate unscheduled downtime by
constantly monitoring and reporting the
exact amount of remaining storage system
useful life.
Numerous SiliconSystems’ patented and
patent-pending
application-specific
technologies can be integrated into
SiliconDrive to safeguard application data
and software IP. Application notes
detailing these performance-enhancing
options are available under NDA.

SiliconSystems’ LifeEst calculation at 100% duty cycle with 25% write cycles.
LifeEst is a comprehensive measurement that considers numerous factors to
determine the projected life span of a SiliconDrive. A white paper that
describes the benefits of LifeEst and how to calculate it can be found at http://
The actual life of a SiliconDrive is dependant on the customer usage model.
SiSMART is a patented technology of SiliconSystems that enables host
systems to monitor actual usage of a SiliconDrive in real time. SiSMART

SIGNAL DESCRIPTIONS
Table 8: Signal Descriptions
Type Description
Signal Name Pin(s)
A2-A0
36, 33,
35
I
Address Inputs. These signals are
asserted by the host to access the task
registers in the device.
-CS0,-CS1
37, 38
I
In the true IDE mode, -CS0 is the chip
select for the task file registers while -CS1
is used to select the Alternate Status
register and the Device Control register.
-CSEL
28
I
Cable Select. This internally pulled-up
signal is used to configure this device as a
master or a slave when the jumper
configuration is in CSEL mode.
When this pin is:
• Grounded by the host, this device is
configured as a master.
• Open, this device is configured as a
slave.

I/O
Data Inputs/Outputs. This is the 8-bit or
16-bit bidirectional interface between the
host and device. The lower eight bits are
used for 8-bit register transfers.
-DMACK
29
39
I
DMA Acknowledge. This signal is used by
the host in response to DMARQ to initiate
DMA transfers. The DMARQ/-DMACK
handshake is used to provide flow control
during the transfer. When -DMACK is
asserted, -CS0 and -CS1 are not asserted
and transfers are 16-bits wide.
DASP
I/O
Disk Active/Slave Present. This open
drain output signal is asserted low any time
the drive is active. In a master/slave
configuration, this signal is used by the
slave to inform the master that a slave is
present.

Table 8: Signal Descriptions (Continued)
Signal Name Pin(s) Type Description
DMARQ 21 DMA Request. This signal is used for DMA
O
transfers between the host and device.
DMARQ is asserted by the device when the
device is ready to transfer data to/from the
host. The direction of data transfer is
controller by -IORD and -IOWR. This signal
is used in a handshake manner with
-DMACK (i.e., the device waits until the
host asserts -DMACK before negating
DMARQ, and reasserts DMARQ if there is
more data to transfer). The DMARQ/
-DMACK handshake is used to provide flow
control during the transfer.

Interrupt Request. This signal is an active
high interrupt request to the host.
27
I
I
I/O Channel Ready. The signal is negated
to extend the host transfer cycle of any host
register access.
-IORD
25
23
Device I/O Read. This is the read strobe
signal from the host. The falling edge of
IORD enables data from the device onto
the data bus. The rising edge of IORD
latches data at the host. The host does not
act on the data until it is latched.
-IOWR
I
Device I/O Write. This is the write strobe
signal from the host. The rising edge of
IOWR# latches data from the data bit
signals. The device does not act on the
data until it is latched.
KEY
20
34
-
Key. Reserved for the Connector Key.
-PDIAG
I/O
Pass Diagnostic. This open drain signal is
asserted by the slave to indicate to the
master that it has passed its diagnostics.

SECTOR NUMBER REGISTER
The Sector Number register is set by the host to specify the starting sector
number associated with the next ATA command to be executed. Following a
qualified ATA command sequence, the device sets the register value to the
last sector read or written as a result of the previous AT command.
When Logical Block Addressing (LBA) mode is implemented and the host
issues a command, the contents of the register describe the Logical Block
Number bits A[7:0]. Following an ATA command, the device loads the register
with the LBA block number resulting from the last ATA command.
