Capacitive Loading Specs on Output Pins
D101* COSC2 OSC2 pin — — 15 pF In XT, HS and LP modes when exter-
nal clock is used to drive OSC1
D101A* C
IO All I/O pins — — 50 pF
* These parameters are characterized but not tested.
† Data in “Typ” column is at 3.0V, 25°C unless otherwise stated. These parameters are for design guidance only and are not tested.
Note 1: In RC oscillator configuration, the OSC1/CLKIN pin is a Schmitt Trigger input. It is not recommended to use an external clock in
RC mode.
2: Negative current is defined as current sourced by the pin.
3: The leakage current on the MCLR
pin is strongly dependent on the applied voltage level. The specified levels represent normal
operating conditions. Higher leakage current may be measured at different input voltages.
4: Including OSC2 in CLKOUT mode.
