Product data sheet
2.1 General features
2.2 Temperature sensor features
2.3 Serial EEPROM features
The SE97 has a single die for both the temp sensor and EEPROM for higher reliability and
supports the industry-standard 2-wire I
TIMEOUT function is supported to prevent system lock-ups. Manufacturer and Device ID
registers provide the ability to confirm the identity of the device. Three address pins allow
up to eight devices to be controlled on a single bus.
