DESCRIPTION
The DS1205V MultiKey has three, 384-bit read/write
data partitions, each protected by its own 64-bit I.D. and
security match fields. The security match field, pro-
grammed by the customer, can never be read from the
DS1205V. An additional security feature, the Intelligent
Response generator, uses invalid security match codes
as the 鈥渟eed鈥?to trigger seemingly valid, yet false
responses to electronic attack.
Communication with the DS1205V is via the Dallas
3-Wire Interface (Data, Clock, Reset). These signals
are under host software control.
The DS1205V MultiKey is designed to be plugged into a
standard 5-pin, 0.1 inch-center SIP receptacle. A guide
is provided to insure proper alignment with the recep-
tacle.
System designers can use the DS1205V to insure that
their valuable firmware can only by run when a valid key
is present. The MultiKey can also contain data on sys-
tem configurations and upgrade options. Designers
may choose to allow maintenance or diagnostic rou-
tines to be run only by an authorized key holder.
See the DS1205S MultiKey Chip data sheet for imple-
mentation details.
