PROGRAMMING PULSE
A typical programming waveform is shown in Figure 10. The user issues a 1-Wire reset followed by a Skip ROMID
command, Match ROMID plus the ROMID, Search or Read Net, the Load Secret command and then the two 32-bit
words to be loaded into EEPROM. 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.
