SILICONDRIVE CF  
SSD-CXXX(I)-3600  
OVERVIEW  
FEATURES  
The SiliconDrive CF 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 8GB  
SiliconDrive technology is engineered  
exclusively for the high performance, high  
reliability, and multiyear product lifecycle  
requirements of the Enterprise System  
• Supports both 8-bit and 16-bit data  
register transfers  
• Supports dual-voltage 3.3V or 5V  
interface  
OEM  
market.  
Typical  
end-market  
14  
applications include broadband data and  
voice networks, military systems, flight  
system avionics, medical equipment,  
• Data reliability <1 error in 10 bits read  
• MTBF 4,000,000 hours  
• ATA-3 compliant  
industrial  
control  
systems,  
video  
• Industry standard Type I CF 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  
8GB  
SSD-C08G(I)-3600  
technologies to virtually eliminate storage  
systems failures.  
PowerArmor prevents data corruption and  
loss from power disturbances by  
integrating patented technology into every  
SiliconDrive.  
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.

* There are unlimited read cycles. Service life is determined using  
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://  
www.siliconsystems.com/resources/Documents/Whitepaper/  
SiliconSystems_NAND_Evolution.pdf.  
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  
measures and reports the remaining life of a SiliconDrive. For more  
information on SiSMART, refer to the Eliminating Unscheduled Downtime by  
Forecasting Useable Life white paper at http://www.siliconsystems.com/

In true IDE mode, this signal is used  
for DMA 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 controlled  
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.

In memory mode, this signal is:  
(PC Card memory

• Set high when the SiliconDrive CF  
is ready to accept a new data  
transfer operation.  
• Held low when the card is busy.  
The host memory card socket must  
provide a pull-up resistor.  
At power-up and reset, the RDY/-BSY  
signal is held low (busy) until the  
SiliconDrive CF has completed its  
power-up or reset function. No access  
of any type should be made to the  
SiliconDrive CF during this time. The  
RDY/-BSY signal is held high  
(disabled from being busy) whenever  
the SiliconDrive CF has been  
powered up with +RESET  
continuously disconnected or  
asserted.  
-IREQ  
I/O Operation. After the SiliconDrive  
CF has been configured for I/O

-DMACK  
In true IDE mode, 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

-CS0 and -CS1 are not asserted and  
transfers are 16-bits wide.  
-RESET

ATTRIBUTE MEMORY DESCRIPTION AND OPERATION  
SSD-CXXX(I)-3600 DATA SHEET  
ATTRIBUTE MEMORY DESCRIPTION AND OPERATION  
The attribute memory plane can be read or written to by asserting the REG#  
signal, qualified by the appropriate combination of CE1#, OE#, and WE#. An  
attribute memory map describing the type and location of the information  
maintained in the attribute memory plane is provided in "Attribute Memory  
Map" on page 24.  
With respect to SiliconDrive CF, attribute memory consists of two sections:  
• Card Information Structure (CIS), which contains a description of the Card’s  
capabilities and specifications.  
• Function Configuration Registers (FCRs), which consists of four registers,  
that can be read or written to by a host to configure the Card for specific  
purposes.  
ATTRIBUTE MEMORY READ OPERATIONS  
Attribute memory read operations are enabled by asserting REG#, OE#, and  
CE1# low. Odd byte read operations from the attribute memory plane are not  
valid.

As stated earlier, the Attribute Memory plane is comprised of two components,  
the CIS and the FCRs. The following tables detail the type, location, and read/  
write requirements for each of the four FCRs maintained in the attribute  
memory plane.

CARD INFORMATION STRUCTURE  
The CIS is data that describes the SiliconDrive CF, and is described by the  
CFA standard. This information can be used by the host system to determine a  
number of things about the Card that has been inserted. For information  
regarding the exact nature of this data and how to design the host software to  
interpret it, refer to the PC Card Standard Metaformat Specification.

accomplished using the ATA Command Block.  
MEMORY-MAPPED REGISTER DECODING  
In memory-mapped mode, the SiliconDrive registers are accessed via  
standard memory references (i.e., OE# and WE#). The ATA registers are  
mapped to common memory space in a 2KB window starting at address 0.

SSD-CXXX(I)-3600 DATA SHEET  
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.

Idle — 97h, E3h  
When issued by the host, the device’s internal controller sets the BSY bit,  
enters the Idle mode, clears the BSY bit, and generates an interrupt. If the  
sector count is non-zero, it is interpreted as a timer count with each count  
being 5ms, and the automatic power-down mode is enabled. If the sector  
count is zero, the automatic power-down mode is disabled.

Read Sector — 20h, 21h  
The Read Sector command allows the host to read sectors 1 to 256 as  
specified in the Sector Count register. If the sector count is set to 0h, all 256  
sectors of data are made available. When the command code is issued and  
the first sector of data has been transferred to the buffer, the DRQ bit is set.  
The Read Sector command is terminated by writing the cylinder, head, and  
sector number of the last sector read in the task file. On error, the read  
operation is aborted in the errant sector.
