DESCRIPTION
The DS1217M is a nonvolatile RAM designed for porta-
ble applications requiring a rugged and durable pack-
age. 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 accom-
plished 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 con-
nector can be used for direct mount to a printed circuit
board. Alternatively, remote mounting can be accom-
plished with a ribbon cable terminated with a 28-pin DIP
plug. The remote method can be used to retrofit existing
systems which have JEDEC 28-pin bytewide memory
sites.
