Conditions
Data in "Typ" column is at 5V, 25°C unless otherwise stated. These parameters are for design guidance only
and are not tested.
Note 1: This is the limit to which VDD can be lowered in SLEEP mode without losing RAM data.
2: The supply current is mainly a function of the operating voltage and frequency. Other factors such as I/O pin load-
ing and switching rate, oscillator type, internal code execution pattern, and temperature also have an impact on
the current consumption.The test conditions for all IDD measurements in active operation mode are:
OSC1 = external square wave, from rail to rail;
all I/O pins tri-stated, pulled to VDD
MCLR = VDD.
3: 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 and VSS.
4: For RC osc configuration, current through REXT is not included. The current through the resistor can be esti-
mated by the formula Ir = VDD/2REXT (mA) with REXT in kOhm.
5: The
current is the additional current consumed when this peripheral is enabled. This current should be
added to the base IDD or IPD measurement.
6: PWRT must be enabled for slow ramps.
7:
ΙLCDT1 and ΙLCDRC includes the current consumed by the LCD Module and the voltage generation
circuitry. This does not include current dissipated by the LCD panel.
