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 high-impedance state and tied to VDD or VSS and all features that
add delta current disabled (such as WDT, Timer1 oscillator, BOR, etc.).
The supply current is mainly a function of operating voltage, frequency and mode. Other factors, such as
I/O pin loading and switching rate, oscillator type and circuit, internal code execution pattern and temperature,
also have an impact on the current consumption. All features that add delta current are disabled (USB module,
WDT, etc.). 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/VSS;
MCLR = VDD; WDT disabled unless otherwise specified.
Low-power Timer1 with standard, low-cost 32 kHz crystals have an operating temperature range of -10°C to
+70°C. Extended temperature crystals are available at a much higher cost.
This is the module differential current when the USB module is enabled and clocked at 48 MHz, but with no USB
cable attached. When the USB cable is attached or data is being transmitted, the current consumption may be
much higher (see Section 23.6.4 “USB Transceiver Current Consumption”). During USB Suspend mode
(USBEN = 1, SUSPND = 1, bus in Idle state), the USB module current will be dominated by the D+ or D- pull-up
resistor. The integrated pull-up resistors use “resistor switching” according to the resistor_ecn supplement to
the USB 2.0 Specifications, and therefore, may be as low as 900 during Idle conditions.
