DS1205S MultiKey Chip

PublishTime：2022-08-10

●DESCRIPTION
■The DS1205S MultiKey Chip is an enhanced version of the DS1204U Electronic Key which has both a standard 3-wire interface (data, clock, and reset) and a 1-wire interface. The DS1205S MultiKey has three secure read/write subkeys which are each 384 bits in length. In addition, there is a 512-bit read/write scratchpad which can be used as a non-secure data area or as a holding register for data transfer to one of the three subkeys. Each subkey within the part is uniquely addressable on byte boundarie.
●FEATURES
■Three secure read/write data partitions of 384 bitseach
■One non-secure read/write data partition of 512 bits
■Secure data cannot be deciphered by reverse engineering
■Guaranteed unique, 48-bit, laser etched serial number
■64-bit password and I.D. fields provide positive identification and security for each secure data partition
■Maximum data transfer rate of 2 million bits/second
■Low-power CMOS circuitry
■Access via 3-wire or 1-wire interface
■Applications include proprietary data, financial trans-actions, secure personnel areas, and systems access control
