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 boundaries.
