2.1 General features
2.2 Temperature sensor features
2.3 Serial EEPROM features
up to eight devices to be controlled on a single bus. To maintain interchangeability with the
I
voltage of 3.0 V to 3.6 V.
DIMM applications normally use the C-grade accuracy SE97PW or SE97TK temp sensor.
For applications requiring the higher B-grade accuracy, the SE97PW/1 or SE97TK/1 is
available.
