Shading of rows is to assist in readability of the table.
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
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.
The test conditions for all I
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.
BOR and HLVD enable internal band gap reference. With both modules enabled, current consumption will be
less than the sum of both specifications.
