Temperature Sensor with Serial Presence-Detect EEPROM
The temperature sensor continuously monitors the module's temperature and can be
read back at any time over the I
2
C bus shared with the SPD EEPROM.

EVENT# Pin
The temperature sensor also adds the EVENT# pin (open-drain). Not used by the SPD
EEPROM, EVENT# is a temperature sensor output used to flag critical events that can
be set up in the sensor’s configuration register.
EVENT# has three defined modes of operation: interrupt mode, compare mode, and
critical temperature mode. Event thresholds are programmed in the 0x01 register using
a hysteresis. The alarm window provides a comparison window, with upper and lower
limits set in the alarm upper boundary register and the alarm lower boundary register,
respectively. When the alarm window is enabled, EVENT# will trigger whenever the tem-
perature is outside the MIN or MAX values set by the user.
The interrupt mode enables software to reset EVENT# after a critical temperature thresh-
old has been detected. Threshold points are set in the configuration register by the user.
This mode triggers the critical temperature limit and both the MIN and MAX of the tem-
perature window.
The compare mode is similar to the interrupt mode, except EVENT# cannot be reset by
the user and returns to the logic HIGH state only when the temperature falls below the
programmed thresholds.
Critical temperature mode triggers EVENT# only when the temperature has exceeded
the programmed critical trip point. When the critical trip point has been reached, the
temperature sensor goes into comparator mode, and the critical EVENT# cannot be
cleared through software.
