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.
