SDP3B FlashDisk Product Manual
SanDisk SDP3B FlashDisk Product Manual © 1998 SANDISK CORPORATION 7
1.0 Introduction to the SDP3B FlashDisk
The SanDisk SDP3B FlashDisk products provide
high capacity solid state flash memory that
electrically complies with the Personal Computer
Memory Card International Association ATA (PC
Card ATA) standard. (In Japan, the applicable
standards group is JEIDA.) The SDP3B FlashDisk
also supports a True IDE Mode that is electrically
compatible with an IDE disk drive. SDP3B
FlashDisks provide up to 220 million bytes
(Megabytes, MBytes or MB) of formatted storage
capacity in a Type II or Type III form factor. The
host system can support as many cards as there are
Type II or III PCMCIA slots.
The SDP3B FlashDisk uses SanDisk Flash
memory chips which were designed by SanDisk
specifically for use in mass storage applications.
In addition to the mass storage specific Flash
memory chips, the SDP3B FlashDisks include an
on-card intelligent controller that provides a
high level interface to the host computer. This
interface allows a host computer to issue
commands to the memory card to read or write
blocks of memory. A block of memory consists of
512 bytes of data and is protected by a powerful
Error Correcting Code (ECC).
The SDP3B FlashDisk on-card intelligent
controller manages interface protocols, data
storage and retrieval as well as ECC, defect
handling and diagnostics, power management and
clock control. Once the SDP3B FlashDisk has been
configured by the host, it appears to the host as a
standard ATA (IDE) disk drive. Additional ATA
commands have been provided to enhance system
performance.

1.1 Scope
This document describes the key features and
specifications of the SDP3B FlashDisk, as well as
the information required to interface this product
to a host system.
1.2 Product Models
The SDP3B FlashDisk is available in 2 to 220
megabyte capacities. All SDP3B FlashDisks are
shipped formatted with a DOS 5.0 file structure.

1.6 The SDP3B FlashDisk Compared
to Previous FlashDisks
The SDP3B FlashDisk is compatible with
SanDisk’s previous FlashDisk products, the SDP,
SDP5, and the SDP5A product. The SDP3B
FlashDisk is not compatible with the SDP5L
which was designed specifically for the HP95LX.
Therefore, the SDP3B FlashDisk is not system
compatible with the HP95LX. For this document,
any of these products are defined as the SDP
Series products. Several improvements have been
added to the SDP3B FlashDisk that do not
appear in previous products. Differences between
the SDP3B FlashDisk and the previous
FlashDisks that could be noticed by previous
FlashDisk users are explained in the following
sections.
