COMPUTATION AND PROGRAMMING
The Compute Next Secret operation waveform is shown in Figure 11. The user issues a 1-Wire reset followed by a
Skip ROMID command, Match ROMID plus the ROMID, Search or Read Net, followed by the Compute Next Secret
command. The system host must connect the low impedance source to the DQ line within time t
D
and for a duration
of time t
SHA
. The DQ line is then pulled to V
PP
for t
PPW
milliseconds and then returned to nominal voltage. The fast
rise and fall time requirements for the programming pulse are required to prevent damage during the transition
between normal communication mode and programming mode.
