SILICONDRIVE CF

SSD-CXXX(I)-3150

OVERVIEW

FEATURES

SiliconDrive

combines

all

the

high

• Integrated PowerArmor, SiSMART, and

SiSecure technologies

performance, high reliability, and multiyear

lifecycle benefits of the standard SiliconDrive

with a comprehensive suite of patented and

patent-pending technologies that provide

multiple security options to safeguard

application data and software IP in embedded

systems.

• Capacity range: 32MB to 8GB

• Supports both 8-bit and 16-bit data register

transfers

• Supports dual-voltage 3.3V or 5V interface

• Data reliability <1 error in 10 bits read

Applications requiring advanced levels of

security such as data recorders, wearable and

field computers, medical monitoring and

diagnostic equipment, POS systems, and

voting machines are able to activate security

options to protect application data and

software IP from theft, falling into the wrong

hands from deployments in high-risk areas,

corruption, and accidental or malicious

overwrites.

• MTBF 4,000,000 hours

• ATA-3 compliant

• Industry standard Type I CF form factor

• RoHS 5 of 6 compliant

• Supports PIO modes 0-4 and DMA modes

0-2

PowerArmor prevents data corruption and loss

from power disturbances by integrating

patented technology into every SiliconDrive.

8GB

SSD-C08G(I)-3150

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.

SiSecure is a comprehensive suite of user-

selectable security technologies that solves

the critical need for robust storage security for

embedded systems applications that have a

small footprint and low-power requirement.

SISECURE

PowerArmor Eliminates drive corruption.

SiZone

Data zones with different

security parameters.

SiKey

Ties SiliconDrive to a specific

host and/or software IP.

SiProtect

Protection software for

password-required, read/write,

or read-only access.

SiSweep

SiPurge

Ultra-fast data erasure.

Non-recoverable data erasure.

* 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/

Type Description

DMARQ

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.

-RDY/-BSY

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

-Interrupt Request. This line is strobed

low to generate a pulse mode

interrupt or held low for a level mode

-CS0 and -CS1 are not asserted and

transfers are 16-bits wide.

-RESET

When the pin is high, this signal

resets the SiliconDrive CF. The

SiliconDrive CF is reset only at power-

up if this pin is left high or open from

power-up. The SiliconDrive CF is also

ATTRIBUTE MEMORY DESCRIPTION AND OPERATION

SSD-CXXX(I)-3150 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.

ATTRIBUTE MEMORY MAP

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.
