Note 1: A device’s I
DD supply current is mainly a function of the operating voltage and frequency. Other factors,
such as PBCLK (Peripheral Bus Clock) frequency, number of peripheral modules enabled, internal code
execution pattern, execution from Program Flash memory vs. SRAM, I/O pin loading and switching rate,
oscillator type, as well as temperature, can have an impact on the current consumption.
2: The test conditions for I
DD measurements are as follows:
• Oscillator mode is EC (for 8 MHz and below) and EC+PLL (for above 8 MHz) with OSC1 driven by
external square wave from rail-to-rail, (OSC1 input clock input over/undershoot < 100 mV required)
• OSC2/CLKO is configured as an I/O input pin
• USB PLL oscillator is disabled if the USB module is implemented, PBCLK divisor = 1:8
• CPU, program Flash, and SRAM data memory are operational, program Flash memory Wait
states = 111, Program Cache and Prefetch are disabled and SRAM data memory Wait states = 1
• No peripheral modules are operating, (ON bit = 0)
• WDT, Clock Switching, Fail-Safe Clock Monitor, and Secondary Oscillator are disabled
• All I/O pins are configured as inputs and pulled to V
SS
•MCLR = VDD
• CPU executing while(1) statement from Flash
• RTCC and JTAG are disabled
3: Data in “Typical” column is at 3.3V, 25°C at specified operating frequency unless otherwise stated.
Parameters are for design guidance only and are not tested.
4: This parameter is characterized, but not tested in manufacturing.
