T&R/T = Tape and reel Straight leads. #Denotes a RoHS-compliant device that may include lead that is exempt under the RoHS requirements. DESCRIPTION The DS2401 enhanced silicon serial number is a low-cost, electronic registration number that provides an absolutely unique identity which can be determined with a minimal electronic interface (typically, a single port pin of a microcontroller) ...

... The idle state for the 1-Wire bus is high. If, for any reason, a transaction needs to be suspended, the bus MUST be left in the idle state if the transaction is to resume. If this does not occur and the bus is left low for more than 120µs, one or more of the devices on the bus may be reset. DS2401 MEMORY MAP Figure 1 8-Bit CRC Code MSB ...

... Presence Pulse(s) transmitted by the slave(s). The Presence Pulse lets the bus master know that the DS2401 is on the bus and is ready to operate. For more details, see the 1-Wire Signaling section. ROM FUNCTION COMMANDS Once the bus master has detected a presence, it can issue one of the four ROM function commands ...

... DS2401. During write time slots, the delay circuit determines when the DS2401 will sample the data line. For a read data time slot “0” transmitted, the delay circuit determines how long the DS2401 will hold the data line low overriding the “1” generated by the master. ...

... DS2401 CRC GENERATION To validate the data transmitted from the DS2401, the bus master may generate value from the data received. This generated value is compared to the value stored in the last the DS2401. If the two CRC values match, the transmission is error-free. ...
