Temperature Sensor with Serial Presence-Detect EEPROM
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 I²C bus shared with the SPD EEPROM. Refer to JEDEC
standard No. 21-C page 4.7-1, "Definition of the TSE2002av, Serial Presence Detect with
Temperature Sensor."
Serial Presence-Detect
For the latest SPD data, refer to Micron's SPD page: micron.com/SPD.

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
