All I/O pins/OSC2 (in RC mode)

—

In XT, HS and LP modes when external

clock used to drive OSC1.

These parameters are characterized but not tested.

Data in “Typ” column is at 5.0V, 25

°C unless otherwise stated. These parameters are for design guidance only and are not tested.

Note

In RC oscillator configuration, the OSC1 pin is a Schmitt Trigger input. It is not recommended that the PIC16F627A/628A/648A

be driven with external clock in RC mode.

The leakage current on the MCLR pin is strongly dependent on applied voltage level. The specified levels represent normal

operating conditions. Higher leakage current may be measured at different input voltages.

Negative current is defined as coming out of the pin.

Includes OSC1 and OSC2 when configured as I/O pins, CLKIN or CLKOUT.
