Notes:

GND = 0 V, TJ = -40°C to 125°C, CL = 50pF

Absolute maximum ratings are stress ratings only, and functional operation at the maximum is not guaranteed. Stress beyond the

maximum rating may affect device reliability or cause permanent damage to the device.

Operating temperature qualified for consumer applications. TJ = TA + qJA x Power. Variables used were

Core Current = 900mA, I/O Current = 200mA, Core Voltage = 1.1 V, I/O Voltage = 3.6 V, TA = 105°C.

If the power supply ramp to full supply time is longer than 10 ms, the POR circuitry will not operate correctly, causing erroneous

operation.
