If the supply voltage is produced by a switching DC-DC converter, ripple should be less than 100 mV peak-to-peak.
Input must be current limited to the value specified. To determine the value of the required current-limiting resistor, calculate
resistance values for positive (V
All functional non-supply pins are internally clamped to V
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 the clock rate is very low which would reduce overall power consumption.
