* These parameters are characterized but not tested.
Note 1: Data in the Typical (“Typ”) column is based on characterization results at 25
°C. This data is for design guid-
ance only and is not tested.
2: This is the limit to which VDD can be lowered in SLEEP mode without losing RAM data.
3: The supply current is mainly a function of the operating voltage and frequency. Other factors such as bus
loading, oscillator type, bus rate, internal code execution pattern, and temperature also have an impact on the
current consumption.
a) 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
VssDD, MCLR = VDD; WDT enabled/disabled as specified.
b) For standby current measurements, the conditions are the same, except that
the device is in SLEEP mode.
4: Does not include current through Rext. The current through the resistor can be estimated by the
formula: IR = VDD/2Rext (mA) with Rext in kOhm.
5: The power down current in SLEEP mode does not depend on the oscillator type. Power down current is mea-
sured with the part in SLEEP mode, with all I/O pins in hi-impedance state and tied to VDD or VSS.
