Temperature Sensor and System Monitor

in a 10-Pin µMAX

_______________________________________________________________________________________ 3

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

of the SCL signal, to bridge the

undefined region of SCL’s falling edge.

Note 3: C

= total capacitance of one bus line in pF. Rise and fall times are measured between 0.3

to 0.7

Note 4: Input filters on SDA, SCL, and ADD suppress noise spikes <50ns.

ELECTRICAL CHARACTERISTICS (continued)
