DS1217M
Nonvolatile Read/Write Cartridge

GENERAL DESCRIPTION
FEATURES
The DS1217M is a nonvolatile RAM designed for
portable applications requiring a rugged and durable
package. The nonvolatile cartridge has memory
capacities from 64k x 8 to 512k x 8. The cartridge is
accessed in continuous 32k byte banks. Bank
switching is accomplished under software control by
pattern recognition from the address bus. A card
edge connector is required for connection to a host
system. A standard 30-pin connector can be used for
direct mount to a printed circuit board. Alternatively,
remote mounting can be accomplished with a ribbon
cable terminated with a 28-pin DIP plug. The remote
method can be used to retrofit existing systems that
have JEDEC 28-pin bytewide memory sites.
