16.4 Supply Current Characteristics
Supply current is mainly a function of the operating
voltage and frequency. Other factors such as I/O
pin loading and switching rate, oscillator type,
internal code execution pattern and temperature,
also have an impact on the current consumption.
Table 16.5 Supply Current in RUN, WAIT and SLOW Mode, 5,5 V supply voltage
Notes:
1. CPU running with memory access, all I/O pins in input mode with a static value at V
2. CPU in WAIT mode with all I/O pins in input mode with a static value at V
3. CPU running with memory access, all I/O pins in input mode with a static value at V
4. Device driven by Internal oscillator at 10 MHz.
5. Not tested in production
