1. A voltage of at least V DDF –0.35 V must be applied at all times to the V PP pin or damage to the FLASH module can occur
The FLASH can be damaged by power on and power off V PP transients. V PP must not rise to programming level while
V DDF is below the specified minimum value, and must not fall below the minimum specified value while V DDF is applied.
2. Current measured at maximum system clock frequency, all modules active, and default drive strength with matching load.
3. Total device current consumption = I DD + I DDSYN + I STBY + I DDF + I PP + I DDA
4. All functional non-supply pins are internally clamped to V SS and their respective V DD .
5. Input must be current limited to the value specified. To determine the value of the required current-limiting resistor,
calculate resistance values for positive and negative clamp voltages, then use the larger of the two values.
6. Power supply must maintain regulation within operating V DD range during instantaneous and operating maximum current
conditions. If positive injection current (V in > V DD ) is greater than I DD , the injection current may flow out of V DD and could
result in external power supply going out of regulation. Ensure external V DD load will shunt current greater than maximum
injection current. This will be the greatest risk when the MCU is not consuming power. Examples are: if no system clock is
present, or if clock rate is very low which would reduce overall power consumption. Also, at power-up, system clock is not
present during the power-up sequence until the PLL has attained lock.
