DETAILED DESCRIPTION
The DS2704 is comprised of an EEPROM memory array and SHA-1 Authentication function that are accessed via
a 1-Wire interface. The 1-Wire interface controls access by a host system to the 64-bit Net Address (ROM ID),
SHA-1 Authentication, 1280-bit EEPROM memory and EEPROM Status.
The DS2704 operates in one of four modes: standby, communication, computation and programming. Standby
mode is the default mode of operation. Whenever any task has been completed, the IC will automatically return to
standby mode. Standby mode is also directly entered if DQ is low for a period of t RSTL . Once standby mode has
been entered, DQ can be returned to logic high and standby mode is retained. Most operations are performed in
communication mode, with the host system addressing the DS2704 using Net Address commands and then
retrieving EEPROM and Status data using memory function commands or setting up an authentication exchange
and retrieving the results. The supply current, I DD1 , varies depending on bus activity, communication direction, and
selection of Standard or Overdrive bus timing.
