PRELIMINARY*  
DimmDrive Solid State IDE Flash Module with Power Failure  
Protection* IDE36  
DimmDrive Solid State IDE Flash Module IDE33  
FEATURES  
GENERAL DESCRIPTION  
The DimmDrive WED7GxxxIDE36 is a high performance  
single chip flash disk IDE module with Power Failure  
Protection Circuit available in 144 Pin SO-DIMM  
package.

144 pin SO-DIMMpackage with IDE pinouts  
Plug-and-play solid state disk  
NAND Flash memory technology by SanDisk  
3.3 V and 5.0 V power supply operation  
16MB – 2GB memory density  
The DimmDrive WED7GxxxIDE33 does not have the  
additional PFP circuit.  
The additional circuit provides protection against accidental  
power loss. This circuit provides an internal power supply  
and control logic to stop receiving data and complete  
writing the last sector of data received. This is not intended  
to be backup for the host system. It will only allow the  
last sector received to finish writing and no more. It will  
improve card integrity in applications with a high risk of  
power failure. The read/write unit is 1 sector (512 bytes)  
sequential access.  
Low power consumption  
ECC error correction  
512 Byte Sector compatible to IDE HD Drives  
Supports true IDE mode  
Commercial temperature range 0°C - +70°C  
PFP Power Failure Protection Circuit (IDE36)  
POWER BACKUP FEATURES (IDE36)  
The module is based on SanDisk NAND Flash technology  
and utilizes 128Mb, 256Mb, 512Mb or 1Gb memory  
components to provide the maximum in module density.

Added PFP circuit built in to preserve card integrity  
during accidental power loss  
PFP circuit may not prevent file/data loss if power  
failure occurs during a long write operation  
The DimmDrive WED7GxxxIDE36/33 utilizes a SanDisk  
Flash ChipSet controller for the SanDisk memory devices.  
This interface allows a host computer to issue commands  
to read or write blocks of memory in the Flash memory  
array. The intelligence to manage the interface protocols,  
data storage and retrieval as well as ECC, defect handling  
and diagnostics are controlled by this device. Automatic  
power management and clock control is handled by the  
controller as well.  
PFP control circuit prevents false operations after  
power loss  
Improves card integrity in applications with a high  
risk of power failure  
Minimum power backup time of 10ms  
APPLICATIONS  
The DimmDrive WED7GxxxIDE36/33 module will have  
the same functionality and capabilities of an intelligentATA  
(IDE) disk drive. Once the device has been configured  
by the user, it appears to the host as a standard ATA disk  
drive.

The on-board controller is a highly integrated solution  
designed to handle all intelligent operations, even the rare  
cases when new defects arise and need to be mapped  
out or replaced by a spare. The hardware performs the  
complicated task of ECC detection and correction and will  
return good data to the host. The controller manages all  
defects and errors and makes the Flash memory appear
