DS1922E
iButton High-Temperature Logger with
8KB Data-Log Memory
ing in the command code, the target addresses TA1
and TA2, and all the data bytes. The DS1922E transmits
this CRC only if the data bytes written to the scratchpad
include scratchpad ending offset 11111b. The data can
start at any location within the scratchpad.
With the Read Scratchpad command, the CRC is gen-
erated by first clearing the CRC generator and then
shifting in the command code, the target addresses
TA1 and TA2, the E/S byte, and the scratchpad data
starting at the target address. The DS1922E transmits
this CRC only if the reading continues through the end
of the scratchpad, regardless of the actual ending off-
set. For more information on generating CRC values,
refer to Application Note 27.

DESCRIPTION
1-Wire reset pulse generated by master.
1-Wire presence pulse generated by slave.
Command and data to satisfy the ROM function protocol.
Command "Write Scratchpad."
Command "Read Scratchpad."
Command "Copy Scratchpad with Password."
Command "Read Memory with Password and CRC."
Command "Clear Memory with Password."
Command "Forced Conversion."
Command "Start Mission with Password."
Command "Stop Mission with Password."
Target Address TA1, TA2.
Target Address TA1, TA2 with E/S byte.
Transfer of as many data bytes as are needed to reach the scratchpad offset 1Fh.
Transfer of as many data bytes as are needed to reach the end of a memory page.
Transfer of 8 bytes that either represent a valid password or acceptable dummy data.
Transfer of 32 bytes.
Transfer of an undetermined amount of data.
Transmission of one FFh byte.
Transfer of an inverted CRC-16.
Indefinite loop where the master reads FF bytes.
Indefinite loop where the master reads AA bytes.
Interval during Copy Scratchpad where the DS1922E does not respond. Any bits read during this time
are logic 1.
