MD2203 ETC, MD2203 Datasheet - Page 6

• Manufacturer Part Number: MD2203
• Description: Disk Onchip 2000 DIP
• Manufacturer: ETC

Easy to Integrate
Fast integration is ensured by the following DiskOnChip 2000 features:
•
•
•
•
•
Robust Error Correction
The DiskOnChip family utilizes a Reed-Solomon Error Detection Code (EDC) and Error Correction
Code (ECC), providing the following error immunity for each 512-byte block of data:
•
•
•
•
High Reliability
DiskOnChip 2000 can be inserted into standard DIP sockets, eliminating the need for mechanical
disk drives, bulky ribbon cables and connectors. The design of DiskOnChip 2000 ensures high
reliability even when subjected to levels of shock, vibration, and temperature changes that would
destroy a conventional magnetic disk drive.
High Speed
DiskOnChip 2000 implements an integrated architecture for data transfers, which eliminates
bottlenecks typical in this area. Additionally, it doubles read performance and significantly improves
write performance, in comparison to competitive alternatives. DiskOnChip 2000 can sustain system
write speeds of over 550KB per second, read speeds of more than 1.4MB per second (measured in
ISA no wait state environment) and read/write burst transfer rates of nearly 5MB per second.
Compatibility with 8MB DiskOnChip Millennium Series
DiskOnChip 2000 is a 32-pin Dual Inline Package (DIP) that provides 100% pinout compatibility
with M-Systems' DiskOnChip Millennium DIP (8MB). DiskOnChip 2000 is fully software
compatible with M-Systems' DiskOnChip Millennium DIP (8MB), for version 1.21 and higher.
Broad Support for Operating Systems and Processors
The DiskOnChip family of products, supplied with TrueFFS firmware, supports a wide range of
operating systems (OS), including DOS, Windows 2000, Windows CE, Windows NT,
Windows Embedded NT, BE, QNX, VxWorks, pSOS, Linux, FreeBSD, PharLap ETS, VRTX and
more.
