WEDC ATA33 Series flash memory cards are ATA
compatible cards and are suitable for usage as a data
storage memory medium for PC's or any other
electronic equipment. This product is built with high
performance NAND memory devices and SanDisk
controller.
Packaged in a PCMCIA type I or type II housing,
the WEDC ATA series cards provide a lightweight,
low power, reliable nonvolatile storage medium.
Built in to the card controller, Error Correcting Code
(ECC) provides a high level of reliability and MTBF
(Mean Time Between Failures).
WEDC's standard cards are shipped with the WEDC
FLASH Logo. Cards are also available with blank
housings (no Logo). The blank housings are available
in both a recessed (for label) and flat housing. Please
contact your WEDC sales representative for further
information on Custom artwork.
NOTE: ATA33 product family is electrically and
functionally compatible with the older ATA30.

Notes:
1.
All values are typical at ambient temperature and nominal supply voltage, unless
otherwise stated
2.
All performance timing asuumes the controller is in the default (I.e. faster) mode
3.
Sleep mode currently is specified under the condition that all card inputs are in static
CMOS levels and in a "Not Busy" operating state.
4.
The current specified, shows the bounds of programmability of the product
