power-up the voltage should be reduced to avoid operation in overdrive mode.
Supply voltage is considered “overdrive” for voltages above 1.47 V. Operation time in overdrive—whether switching or
not—must be limited to a cumulative duration of 1.25 years (10,950 hours) or less to sustain the maximum operating voltage
without significant device degradation—for example, 25% (average 6 hours out of 24 yours per day) duty cycle for 5-year rated
equipment. To tolerate the maximum operating overdrive voltage for 10 years, the device must have a duty cycle of 12.5% or
less in overdrive (for example 3 out of 24 hours per day). Below 1.47V, duty cycle restrictions may apply for equipment rated
above 5 years.
The SR voltage is applied to QVCC, QVCC1, and QVCC4 after the device is placed in SR mode. The Real-Time Clock (RTC)
is operational in State Retention (SR) mode.
Overshoot and undershoot conditions (transitions above NVCC and below GND) on I/O must be held below 0.6 V, and the
duration of the overshoot/undershoot must not exceed 10% of the system clock cycle. Overshoot/undershoot must be
controlled through printed circuit board layout, transmission line impedance matching, signal line termination, or other
methods. Non-compliance to this specification may affect device reliability or cause permanent damage to the device.
The core voltage must be higher than 1.38V to avoid corrupted data during transfers from the USB HS. Please refer to Errata
If the Core voltage is supplied by the MC13738, it will be 1.6 ± 0.05 V during the power-up sequence. This is allowed. After

The term NVCC in this section refers to the associated supply rail of an
input or output. The association is shown in the Signal Multiplexing chapter
of the reference manual.
NVCC6 and NVCC9 must be at the same voltage potential. These supplies
are connected together on-chip to optimize ESD damage immunity.
