Output low voltage — low drive (PTxDSn = 0)
Output low voltage — high drive (PTxDSn = 1)
Maximum total I
DC injection current
Input capacitance (all non-supply pins)
RAM will retain data down to POR voltage. RAM data not guaranteed to be valid following a POR.
This parameter is characterized and not tested on each device.
Measurement condition for pull resistors: V
PTA5/IRQ/TCLK/RESET pullup resistor may not pullup to the specified minimum V
to guarantee that a logic 1 will be read on any port input when the pullup is enabled and no DC load is present on the pin.
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
in external power supply going out of regulation. Ensure external V
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).
