Temperature Sensor and System Monitor
in a 10-Pin µMAX
_______________________________________________________________________________________

Note 1: Total monitoring time includes temperature conversion and four analog input voltage conversions.
Note 2: A master device must provide at least a 300ns hold time for the SDA signal, referred to V
IL
of the SCL signal, to bridge the
undefined region of SCL’s falling edge.
Note 3: C
B
= total capacitance of one bus line in pF. Rise and fall times are measured between 0.3 x V
CC
to 0.7 x V
CC
.
Note 4: Input filters on SDA, SCL, and ADD suppress noise spikes <50ns.
Note 5: Guaranteed but not tested over the entire temperature range.
