Introduction
The PCD-897 DiskOnChip® 2000 Flash PC card is a new solid state disk (SSD) in
a standard 32-pin DIP package. It is a fast and economical Flash disk for embedded systems, Internet devices and portable applications with limited space and modest disk capacity requirements. It features an ISA
connector and can be installed into ISA backplanes, CPU cards and motherboards.
The PCD-897 uses M-Systems' DiskOnChip®2000 single-chip, solid state flash disk. It incorporates a new flash component
technology called NAND. These high density, low cost components enable faster read/write speeds, higher capacities and better prices than previous generations of flash components.
The DiskOnChip® 2000
provides a Flash disk (BIOS expansion only) which does not require any bus, slot or connector. Simply insert the DiskOnChip® 2000 into a 32-pin socket on the PCD-897 or a CPU board and you have a bootable
flash disk. Its low power consumption and small size makes it the optimal solution for single board computers
DiskOnChip® 2000 is bundled with M-Systems' industry standard TrueFFS® (True Flash File
System) software for full read/write disk emulation.
TrueFFS® provides hard disk compatibility at both the sector and file level. It works in a variety of operating system environments including DOS, Windows 95, pSOS+ and QNX. In addition, TrueFFS® incorporates features that ensure data integrity and reliability.
M-Systems currently manufactures DiskOnChip® 2000 products at capacities from 2 to 144 MB. Users of our DiskOnChip® 2000 modules will be able to upgrade to the higher capacity chips as M-Systems
has committed to retaining the same pin-out. This assures that the future higher capacity chips can be installed into our solid state devices.
