† NOTICE: Stresses above those listed under “Absolute Maximum Ratings” may cause permanent damage to the
device. This is a stress rating only and functional operation of the device at those or any other conditions above those
indicated in the operation listings of this specification is not implied. Exposure to maximum rating conditions for
extended periods may affect device reliability.
Note 1: Power dissipation is calculated as follows: Pdis = V

2: Voltage spikes below V
3: PORTD and PORTE are not implemented on the 28-pin devices.
ELECTRICAL CHARACTERISTICS
a series resistor of 50-100 should be used when applying a “low” level to the MCLR pin, rather than pulling
this pin directly to V
