Supply Currents
This section describes the current consumption characteristics of the device as well as the conditions for
the measurements.
A.1.10.1
Measurement Conditions
All measurements are without output loads. Unless otherwise noted the currents are measured in single
chip mode, internal voltage regulator enabled and at 16MHz bus frequency using a 4MHz oscillator.
Table A-7. 3.3V I/O Characteristics
Conditions are VDDX=3.3V +/-10%, Temperature from –40C to +140C, unless otherwise noted
