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
Does not include analog module pins. Dedicated analog pins should not be pulled to V
used to reduce current leakage.
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
If positive injection current (V

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.
Run at 1 MHz bus frequency
Low voltage detection and warning limits measured at 1 MHz bus frequency.
