not tested.

Note 1:

This is the limit to which VDD can be lowered in SLEEP mode without losing RAM data.

The supply current is mainly a function of the operating voltage and frequency. Other factors such as I/O pin loading and

switching rate, oscillator type, internal code execution pattern, and temperature also have an impact on the current con-

sumption.

The test conditions for all IDD measurements in active operation mode are:

OSC1=external square wave, from rail to rail; all I/O pins tristated, pulled to VDD or VSS, T0CKI = VDD, MCLR = VDD;

WDT disabled.

Current consumed from the oscillator and I/O’s driving external capacitive or resistive loads needs to be considered.

For the RC oscillator, the current through the external pull-up resistor (R) can be estimated as: VDD / (2

• R).

For capacitive loads, the current can be estimated (for an individual I/O pin) as (CL

• VDD) • f

CL = Total capacitive load on the I/O pin; f = average frequency the I/O pin switches.

The capacitive currents are most signiﬁcant when the device is conﬁgured for external execution (includes extended

microcontroller mode).

The power down current in SLEEP mode does not depend on the oscillator type. Power-down current is measured with

the part in SLEEP mode, with all I/O pins in hi-impedance state and tied to VDD or VSS.

For RC osc conﬁguration, current through Rext is not included. The current through the resistor can be estimated by the

formula IR = VDD/2Rext (mA) with Rext in kOhm.
