Description The DiskOnChip MD2202 product line is the second-generation of M-Systems! DiskOnChip series of products. The MD2202 series provides a small, single-chip, solid-state flash disk in a standard 32-pin DIP package. Combining a disk controller with flash memory on a single chip, DiskOnChip MD2202 is the solution where minimal weight, space, and power consumption are essential. In consequence, the MD2202 series finds use today in a wide range of products, such as information appliances, set-top boxes, thin clients, thin servers, network computers, and embedded,portable computers.
By placing DiskOnChip MD2202 in a standard socket, physical space requirements are reduced. Unlike standard IDE drives, no cables or extra space are required. DiskOnChip MD2202 has no moving parts, resulting in significantly decreased power consumption and increased reliability. It is easy to use and reduces integration overhead. DiskOnChip MD2202 is therefore a very attractive alternative to conventional hard and floppy disk drives
