† 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:
Note 1: Power dissipation is calculated as follows:
2: Voltage spikes below V
ELECTRICAL CHARACTERISTICS
Other than some basic data, this section documents only the PIC18F2423/2523/4423/4523 devices’ specifi-
cations that differ from those of the PIC18F2420/2520/4420/4520 devices. For detailed information on the
electrical specifications shared by the PIC18F2423/2523/4423/4523 and PIC18F2420/2520/4420/4520
devices, see the “PIC18F2420/2520/4420/4520 Data Sheet” (DS39631).
