DiskOnChip 2000 DIP
Overview
M-Systems DiskOnChip 2000 is a high performance flash disk in a standard 32-pin DIP. This unique data storage solution offers cost effective data storage beyond that of traditional hard disks. Perfect for applications with limited space and varying capacity requirements. The DiskOnChip 2000 is simply integrated into your CPU board and you have a bootable flash disk.
Optimal Solution for Internet Appliances, Thin Clients & Embedded Mother Boards
The DiskOnChip 2000 has become the standard modular flash disk for Internet Appliances (such as set-top-boxes) and embedded single board computers.
TrueFFS
TheDiskOnChip 2000 includes M-Systems proprietary TrueFFS (True Flash File System) technology built-in, providing complete read/write capability and hard disk emulation. TrueFFS provides hard disk compatibility at both the sector and file level. The DiskOnChip 2000 works in all major operating systems including Windows CE, Windows XP, VxWorks, Linux, QNX, DOS and more. It is also relatively easy to customize to work in O/S-less and non-x86 environments.
Reliability
The use of TrueFFS, in conjunction with the built-in EDC/ECC, provides maximum data reliability, even under harsh operating conditions such as power failures. Advanced wear leveling ensures long flash life for maximum usage.
