Datasheet

Note 1: Limits are 100% production test at T
A
= +25°C. Limits over the operating temperature range and relevant supply voltage
range are guaranteed by design and characterization.
Note 2: All voltages referenced to GND. Currents entering the IC are specified positive and currents exiting the IC are negative.
Note 3: Maximum current assuming 100% CPU duty cycle.
Note 4: The value does not include current in GPIO, SCL, SDA, MSDIO, MSDI, MSCL, REFINA, and REFINB.
Note 5: Using 2.5V internal reference.
Note 6: There is one internal oscillator. The oscillator (peripheral clock) goes through a 2:1 divider to create the core clock.
Note 7: Guaranteed by design.
Note 8: Tested at worse-case positions.
Note 9: Default or slower ADC clock settings.
