Typical values are measured at 25°C. Characterized, not tested
As the supply voltage rises, the LVD circuit will hold the MCU in reset until the supply has risen above V
Measured with V
All functional non-supply pins are internally clamped to V
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.
Power supply must maintain regulation within operating V
conditions. If positive injection current (V
result in external power supply going out of regulation. Ensure external V
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).
Maximum is highest voltage that POR is guaranteed.
