1 Typical values are measured at 25
°C. Characterized, not tested
2 As an exception, the Fast Ethernet Controller (FEC) is only operational above the operating voltage of 3 V.
3 As the supply voltage rises, the LVD circuit will hold the MCU in reset until the supply has risen above V
LVDL.
4 All functional non-supply pins are internally clamped to V
SS and VDD.
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 (VIn > VDD) is greater than IDD, the injection current may flow out of VDD and could result
in external power supply going out of regulation. Ensure external VDD 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).
7 Maximum is highest voltage that POR is guaranteed.
8 Low voltage detection and warning limits measured at 1 MHz bus frequency.
9 Run at 1 MHz bus frequency
