Device Typ Max Units Conditions
Note 1: 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 V
DD or VSS and all features that add delta
current disabled (such as WDT, Timer1 oscillator, BOR, etc.).
2: 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 I
DD measurements in active operation mode are:
OSC1 = external square wave, from rail-to-rail; all I/O pins tri-stated, pulled to V
DD;
MCLR
= VDD; WDT disabled unless otherwise specified.
3: 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.
4: Voltage regulator disabled (ENVREG = 0, tied to V
SS).
5: Voltage regulator enabled (ENVREG = 1, tied to V
DD), REGSLP = 1.
6: 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 22.6.4 “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 900Ω during Idle conditions.
