EMC1501 Memory Module Temperature Sensor and Serial Presence Detect EEPROM PRODUCT FEATURES Data Brief General Description Applications The EMC1501 is a combination temperature monitor and Serial Presence Detect (SPD) EEPROM compatible with the TSE2002av JEDEC Specification. It contains an internal temperature monitor as well as an integrated 2k bit EEPROM with two methods of software protection. This product is different from other devices in that it can operate at any of three voltage ranges (1.8V, 2.5V, or 3.3V). It provides accuracy beyond the JEDEC requirements and offers 1°C accuracy from 25°C to 100°C. The low current consumption can be reduced using the software programmed shutdown mode. The EMC1501 contains programmable high, low, and critical temperature limits. Finally, the device EVENT pin can be configured as active high or active low and can be configured to operate as an interrupt or as a comparator output.
