Temperature Sensor With SPD EEPROM

The temperature sensor continuously monitors the module's temperature and can be

read back at any time over the I

C bus shared with the serial presence-detect (SPD) EE-

PROM. Refer to JEDEC JC-42.4 EE1004 and TSE2004 device specifications for complete

details.

SPD Data
