These parameters are for design guidance onlyand 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 pinloading and switching rate, oscillator type, internal code execution pattern, and temperature also have animpact 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 tristated, pulled to VDD, T0CKI = VDD,MCLR = VDD; WDT enabled/disabled as specified.3: The power down current in SLEEP mode does not depend on the oscillator type. Power-down current ismeasured 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 beestimated 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 beadded to the base IDD measurement.DS35007A-page 44 Preliminary © 1998 Microchip Technology Inc.
