Unfortunately, almost no information is available about this chip
except that it ships in an 8-pin package. Are you sure the chip
supports two external temperature sensors like EMC1403 ?
The chip numbering and the number of pins would suggest that
it only supports a single external temperature sensor,
which would make it compatible to emc1402/emc1422.
