Note 1:

This table details the power consumption of the UPD301A device as measured during various modes of

operation. Refer to Section 4.2, "Power States" for additional information. Power dissipation is determined

by temperature, supply voltage, and external source/sink requirements. Maximum values represent very

short bursts of activity over a small amount of time. Typical values represent averaged current consump-

tion over time.
