Terminated via internal/

external interrupt or a reset

These parameters are characterized but not tested.

†

Data in “Typ” column is at 5V, 25

°C unless otherwise stated. These parameters are for design guidance only

and are not tested.

‡

These parameters are for design guidance only and are not tested, nor characterized.

Note 1: In RC oscillator conﬁguration, the OSC1/CLKIN pin is a Schmitt Trigger input. It is not recommended that the

PIC17CXX devices be driven with external clock in RC mode.

2: The leakage current on the MCLR pin is strongly dependent on the applied voltage level. The speciﬁed lev-

els represent normal operating conditions. Higher leakage current may be measured at different input volt-

ages.

3: Negative current is deﬁned as coming out of the pin.

4: These speciﬁcations are for the programming of the on-chip program memory EPROM through the use of the

table write instructions. The complete programming speciﬁcations can be found in: PIC17CXX Programming

Speciﬁcations (Literature number DS30139).

5: The MCLR/VPP pin may be kept in this range at times other than programming, but is not recommended.

6: For TTL buffers, the better of the two speciﬁcations may be used.

Note:

When using the Table Write for internal programming, the device temperature must be less than 40˚C.
